gear timing on assembly? think about it.. if you pull your trigger and release it before a cycle finishes... where does the sector gear end up? Somewhere mid cycle. Could be anywhere from not engaged on the piston to fully engaged mid pull on the piston to full cock before it releases.
What happens when you pull the trigger again? it finishes cycling, doesn't matter where the gears sit, it will go. The tappet peg is fixed, and the sector segment are fixed, all other teeth are fixed ratio, it's like asking where the bottom of a circle is. It's not like you have a cam with multiple pistons being pulled at different intervals.
As long as you didn't mesh your sector halfway through a piston cycle... which is highly unlikely you could reassemble the gearbox with out all the parts blowing up trying to get the 2 halves together because it's under tension.
