Agreed constant hand speed is assumed in the endless belt analogy for illustrative purposes only. Actual constant hand speed when swinging would imply no rate of acceleration therefor no Lag Pressure wouldn't it? Something a few GSED's got wrong maybe? You don't want to swing the hands at a constant speed......and how could you do that anyways? Slow and steady acceleration may feel like a constant hands speed however...

what??? of course there would be lag pressure ob, they didnt get it wrong. YOU DO WANT TO SWING THE HANDS AT A CONSTANT SPEED, you move them at the same speed, you are not speeding up down there, constant hand speed is not hard at all, why are you guys saying constant hand speed is not possible???

When snap releasing, the hands slow precipitously in the release interval. They also slow in a sweep release, but not as dramatically. Constant hand speed exists only in the endless belt model.

according to what information do you make this statement?
