It does however affect FPS consistency as back and forth play will affect where the BB seats in the chamber.

I am referring to where the nozzle slides into the front tappet groove (not the tappet plate itself), sometimes the nozzles are tight and level with little lateral movement (the tappet and nozzle become almost like one solid piece if it fits well), other times you can see significant nozzle play and any upward spring pressure on that nozzle at full extension will push it out of alignment. A tight fit in this groove counteracts this pressure and does not let the nozzle flex upwards as much.
