piston 2nd tooth removal?

I have heard about this a little, and have only gotten answers that are a little sketchy.
from what I understand it is to allow the sector gear to properly mesh, otherwise it can bottom the piston out and strip the teeth on the piston.
am I thinking correctly? and when and how should I know when I need to alter the piston?
thanks.

Taking out the 2nd last tooth allows for some room for error if (under excessive high ROF) your gears begin their second cycle before the piston is returned to battery from it's first cycle... I'm sure you can imagine what happens when a forwards-moving piston meets backwards-turning steel HS gears moving at 30 revolutions per second - it's strips out ALL the piston teeth, and usually rips the end off the piston.

See this link for an image showing the missing last tooth on the Angel High Speed piston:

i think this could answer your questions.

well thanks for the input guys.
see I had a piston fail on me, and th first two teeth looked fine, it was the next 4 or 5 that were all stripped. So then I heard about if the piston teeth and the sector gear teeth do not mesh properly. it will strip out the middle teeth on the piston. I do not want to throw pistons at this gear box again and again.
so I am thinking this might have been the problem.
Is it fine on any piston in any gear box, to just remove that second tooth all the time? or is there a drawback?

It should work on all gearboxes. I have pistons modified this way in almost all my guns.
