As far as I know, no one with any expertise has stated equivocally under which conditions that it is SAFE to ignore 20 IPS guide on piston speed.

I typically choose to considered it likely to be deemed unsafe by thoughtful robot inspectors unless an expert vouches for the SAFETY of the configuration.

If leaving a piston attached to a "bow" when shooting an arrow is an engineering acceptable use of pneumatic piston, will someone with expertise in the failure modes of actuators please confirm?
I for one would like to see a bright-line rule that robot designs must have external stops to prevent the pistons from colliding with the endcaps of the cylinders, regardless of whether this 20ips rumor is authentic or authoritative.

That's the safest approach, and gives the inspectors clear guidance.
