I would have liked you to check the Specto Data and compare what it was showing to your calculations.

[@brunsnick]

It’s all over the map. It could change and vary based on what color ball I throw.

[@remington1439]

I didn’t know the color of ball would make that change. I have been told that a solid white ball is the best like the widow white moves better. IDK , but you give great info

[@MrZJK541]

Actually the compound used in purple balls makes them one of the best on lane! It's actually one of the reasons why the purple hammer was so dominant for so long!@@remington1439

Awesome video, glad I messed around with this with someone a few days ago who was trying to figure out his pap, (he put tape on my ball where my pap was but i just left it on there while recording cause I liked watching it spin!🤣🤣) if i did these calculations correctly i am at 300 RPMs, somewhere in there I believe, and launch speed is 15 mph, honestly thought I wasn’t getting much on the ball but knowing i’m right at 300 rpms makes me happy 🤣will do an update on this later when i have the camera set up the proper way.

[@brunsnick]

Proper camera setup might net you another 10rpms, never know! 😁

[@greggas1]

Good point about watching the shadow of the ball crossing the foul line. Not everybody releases the ball at the same place, some are farther back than others. Also, I've never been sure how standardized the lane markings are. You said 15ft was at the 3rd arrow (the base or tip?). At the 2 houses I've measured, 15ft was right between the tip of the 2nd arrow and the base of the 3rd.

[@brunsnick]

15’ was dead center here. If it’s off by a lil bit, that’s fine. Ball park numbers are good enough. iPhone also has a measuring app which is pretty handy.

[@williamwalters3796]

Omg it’s THE greggas1

[@spgspg6503]

Thanks Nick

[@Jbmccain86]

This is how I do it! I do use an app called frame grabber where I can break down the video by frame which helps a lot! I also made a spreadsheet and its setup to only enter the release time, the time of first rotation, time at dots, time at arrows and time at head pin. From that it will tell me my revs, Ave speed to dots, Ave speed to arrows, and average speed to pins.

[@rigogv1]

Great can you share your spreadsheet ?

[@jah5r]

I did the same thing with some graphs for good visual representation for my personal accuracy. Numbers is nice because I don’t have to input the numbers in the spreadsheet once I build it. It’s an input window so it feels like an app.

[@garyhodge9250]

Great video. I’ve used SPECTO at lanes where it is offered or lessons at the ITRC. The latter is not cheap. This method is a great tool to test how well you are progressing in training with skills like loose arm swing and the “yo-yo” release.

[@brunsnick]

SPECTO is great for positioning and speed info, but rev rate calculation is all over the place.

[@garyhodge9250]

@@brunsnick Interesting. I remember at the ITRC they said that ball color affected the accuracy of rev rate.

[@SovietWarMusic]

@@garyhodge9250Yep, tried specto and it was all over, but its the worst with solid colored ball. My rev rate is 180ish and I threw my Pitch Black at a 10 pin killing my wrist, said I had 480 lol

[@topgunne12]

Nick posted faster than I ever could - was waiting for the Reddit posts on speed/rev checks 😂

[@brunsnick]

Now they can all be directed here. I think the biggest thing is just getting the video filmed properly first. I see so many vids where nothing can be made out properly.

[@newbloodink]

1)Another great video, BrunsNick #1 Hype #2. 2) How often are you check these stats including PAP? Dont think my PAP has changed considering everything ball i drill rolls similarly (different layouts)

[@brunsnick]

Doesn’t hurt to check it once a year or whenever you make a grip change.

[@rayjayks]

The speed monitors in bowling centers in addition to only measuring near the pin deck are also all over the place in accuracy. I see 2 mph differences between the two lanes on the same pair in some cases.

[@notonyourlife7939]

Yeah, they're worthless for determining actual ball speed... but it will let you know if your ball speed is consistent or not, and give you a reference point for good shots vs bad shots. Both of which are far more useful for improving your game than having an "accurate" number for your ball speed. The number by itself doesn't help you much... but if you're fluctuating all over the place, you know your game has a problem.

[@crimsontide1980]

Yep I've noticed the same thing. I'm generally in the 17's on my strike ball, and one night in league play my strike ball was like 18.4-18.7. I was like hell, I must be feeling really loose tonight 😂😂. But my teammate who's usually upper 14-lower 15 range was hitting 16.5 on the screen so I'm assuming that it was just reading fast for everyone on that pair of lanes. But I will say the carrydown was much farther than the last few weeks so less friction/more speed I'm guessing, even though I was attempting to back off my speed a bit to give the ball time to hook up with the lane since it was so slick.

[@rafabonati7757]

I am planning to use the patented Brunsnick Shoe Tripod on Friday.

[@BrunsBrent]

I cant wait to use this method to calculate my 265 rev rate.

[@brunsnick]

I said 250 🤣

[@BudHeavy64]

Since you mentioned Reddit…..is this explaining the process that u/greggas1 uses when people ask for a rev check in r/bowling? Or is this an alternative? Love the videos!!

[@brunsnick]

Not really sure his process, this is 24/7 resource for those that want to check and how to set up the shot and calculate it.

[@CodyLeslie]

This would be slightly different in terms of revs, at least based on his explainers. He counts more directly, how many frames for one revolution. Tape not necessary if there is enough contrast in the ball color to track. The speed calculations are basically the same method.

[@greggas1]

Huh! My other reply disappeared. Brunsnick is measuring the time for 1 rotation directly. The calculator I put together docs.google.com/spreadsheets/d/1Wl4y1jag2V3Rd-0EJYX9iyNnNq_e4qjHmxa3TmCllYE/edit#gid=119273129 divides the FPS by the number of frames for 1 rotation, to get your rotations per second. Then, it multiplies by 60 to get your RPM (REV Rate Method 1).

[@crimsontide1980]

Awesome, I finally figured out my rev rate after years of guessing what it was. Was estimating about 550 and come to find out it was only 518, which is fine, the older I get the less I care about power or ball speed. So when the pros bowl on TV and it shows their ball speed, is it calculating their ball speed to the pins or their launch speed? Because most the pro bowlers, when theyre on a TV telecast their ball speed they show on TV is usually 19-21 miles an hour which is pretty insane if thats their ball speed when it crashes into the pins. Think mine usually reads out about mid 17ish and from what youre saying, the scoreboard readouts are showing ball speed when it hits the pins, so I'm not sure my launch speed yet but I'll have to calculate that as well.

[@brunsnick]

Launch speed. First 10-15 feet on TV.

[@liquidrock2u]

For finding out your ball speed, wouldn't you want to match up the ball position with the arrows when the ball meets the same position as the right most arrow? Since the arrows aren't in a straight horizontal line, so the numbers are off a bit.

[@brunsnick]

Technically yes, but unless you need your ball speed to be accurate to fractions, doesn’t really matter. At 5 boards left of 3rd arrow, that makes the hypotenuse 15.008”.

[@jcc_482]

To put it simply, "you're the best!"

[@ripvanrevs]

I'll have to calculate this with my thumb in the ball. I'm around 400 revs with my thumb out. Probably way under 300!

I'm happy to see I'm not the only shoe tripod guy

[@brunsnick]

[@robertbishop86]

Great video. I have my ball specs that say my PAP is 5 3/4 by 1 1/4 up. How do I mark this without an armadillo or the measuring protractor? I’m a 70 year old bowler who still wants to learn an get better.

[@brunsnick]

Guesstimate the over and up from center of grip and mark it with tape. Throw a few shots on camera to verify that the tape is on the PAP at the point of release. Adjust tape as needed. 👍🏻

[@leviharris5603]

So exactly what are u using to play videos back or app. I used my son's phone which is a newer iPhone and I can't watch it in tenths of seconds like yours

[@brunsnick]

Go into photos, find the video, click edit, and scrub.

[@MikeDCWeld]

Alternatively, you could simply plug your feet per second value into a unit converter to get miles per hour.

[@brunsnick]

Sure could but math is fun.

[@quietguy5468]

I have been using my shoe for quite some time.

[@TheWildwoodPicker]

idk if I missed this in the begining of the video or not; I'll check again, but how do you know where your PAP is located on the ball? What is the correct way to find that? Thank you.

[@brunsnick]

If you don’t have specialized tools, you can guesstimate the location based on the initial oil ring, place a piece of tape on the axis and adjust as you throw it.

[@TheWildwoodPicker]

@@brunsnick Thank you... I'm getting a couple of balls drilled on Friday I'll have my Pro Shop guy show me where to mark all my bowling balls so I can try this out on all of them. I have a Teal Rhino Pro as my main ball but I have a hard time seeing the oil rings on my ball most of the time. I've seen it few timesoccasionally, but for some reason it's not there after each shot.

[@brunsnick]

Try and play towards the middle of the lane where the most oil is. Sometimes it helps to lightly scuff the ball. Your pro shop should definitely be able to help you locate your PAP once you have fresh oil rings. Mark the spot, then record a few shots to confirm. 👍🏻

[@TheWildwoodPicker]

@@brunsnick I'll give that a try too. Thank you for all your help, it's very much appreciated.

[@traviskirk3834]

On the monitor after 4 frames it says my average speed is 17.5 mph while when I throw it hard and straight is usually 23-24 mph but the hardest has been 27.5 mph . How much does the ball slow down from the time it leaves your hand till the head pin.

[@brunsnick]

Depends, but usually 20-25%.

[@hpurey]

Would have been interesting to compare launch speed to the speed registered at the pins.

[@brunsnick]

I do every ball review video. About a 20-25% drop.

[@hpurey]

[@34e321]

What is your axis ? And how do you determine your grip center since you use sarge?

[@brunsnick]

4.5x0.5 up. Center of grip determined measuring back from PAP. I know the spans are different but that’s what I go off.

[@34e321]

@brunsnick cool ty. I didn't know if you measured off of the ring or middle or the average of the 2 spans.

[@brunsnick]

Yeah, when I drill I got middle finger, thumb, ring in that order.

[@34e321]

Well if you determine your grip center based on thumb to ring or thumb to middle that's going to change your Up or down coordinate on your val. Since the grip center is half the span. Half of ring and middle span are quite different for you only in this case.

[@brunsnick]

The other "pro" is trying to get me to buy the most expensive stuff...How do I find out rev rate, ball speed, etc. to get the proper layout? I just buy a ball, get my hand measured, have the ball drilled, then after PAP, etc, is known have the ball plugged and redrilled/laid out?
