Don't bother optimizing it. To prove me wrong you only have to show that either of these claims is wrong, even slightly:

1. The average of the total force applied to the pipe is identical to the average force applied by the mass.

2. For a 100kg 40m/s mass, the average force applied by the mass is 8000Ns / turnaround time.

Im using the spring co efficient as a resistive force.

It isn't a force. You have to multiply it by the amount of spring deflection to get the force.

Cool. I'm glad you're actually trying it. I just hope that when it fails you don't make some excuse about too many strokes or not fully using the intake vacuum or whatever.
