Wow, this looks like a #Series, dude! First Why, now How - so cool. Racket #Yaw/SwivelFlip around CoG .... this is #GOLD! Pronation next ... that could be #Diamond, can't wait! ;) You are almost as inspiring as Dr. Brian GORDON (he missed the #YawSwivel secret, though) and Chuck TOMLIN (the #swivel guy). Even more motivating, I would add ;) Currently I am a bit busy with 'exotic' WTA-FHs: straight-arm FHs of Leylah Fernandez, Emma Navarro and others, ATPtypeFH of Emma Raducanu and Jr. FEDerica. Hope to tackle the ATPtype3 FH 'secrets' by the end of this year, time allowing. You are such an inspiration, keep it up, bro! :)

2:11 MSc engineer here. The pen spins around its centre of frictional resistance - not its centre of gravity (perfectly flat pen, perfectly flat table). Your analogy is pseudo-science. If the tip of the pen were rough and sitting on rough material and the shaft were super-slidey, it would rotate around the tip.
