then if give reduce stroke. 4mm stroke + 50% give = 2mm stroke ?? if thats correct, a machine with a long stroke and 100% give, = machine with no give and many stroke cams?

You are correct, sort of... I was going to bring up that point, but I am not here to argue... something with 100% damping (give) would result in 0% end stroke. A machine with 100% give would not penetrate into the skin... so it would equal 0mm stroke cam.

Give, or the technical term "dampening or damping"... works the same as a shock absorber... a shock with 100% damping would absorb the entire impact, and sitting in your car, you would not feel it.

4mm stroke with 25% damping = 3mm end stroke with less impact
4mm stroke with 75% damping = 1mm end stroke with very little impact

The impact can be measured in Newtons (N)
