Why isn't anyone talking about this amazing S1H feature?

Just got in my S1h today and immediately took it out shooting. I would have loved to have a professional project to use it on today, but shooting my son worked just as well.
One of the things that really caught my attention when I watched the Gerald Undone review on this camera, is he mentioned that when using the S35 mode on this camera, the rolling shutter drops significantly to around 12-13ms. The s5 is even faster at around 10ms.
This is a very fast rolling shutter speed, only really beaten by some of the higher end cinema cameras, or a few of the newer Sony cams with very fast readout speeds. This is around the same as the Arri Alexa LF in fact, which is pretty amazing.
Anyways, I put it to the test in this video, and was really impressed with both the quality of the footage regarding sharpness, detail, and overall look, as well as the quality of the movement. Check it out and let me know what you think.
