I don't understand. Admittedly, I always use the ends of my fingers, but from the video it looks pretty clear to me that his (Massimiliano Iovane's) fingers (only the parts of the fingers closest to the palm, but it's still the fingers) are in fact touching the sensors. So why isn't this legal?
I suppose it's possible that the angle is making it look like his fingers are touching the timer when in fact they are not, but I certainly wouldn't consider this video clear evidence of a +2. Am I misinterpreting the rules?
