xb1 controller analog problems(aka 1 of 1000)

[steamjunk1997]

ok in metroid prime the L-analog works to lock samuss view onto a pivot point
to be clear im not talking about the L-digital button to lock onto an enemy

but if i have both L-analog and L-digital mapped to the xb1 controllers L-trigger as it should be
then when i hit the controllers L-trigger to fast dolphin misses it entirely
but if i dont have L-digital mapped to L-trigger i can try to hit it as fast as i can and dolphin never misses it

i dont think it can be attributed to input lag so what could it be?
