How fast "button press" can Oculus Pro Controller track (X,Y,A,B)?

Hi,

We are developing a Rocket launcher simulator and we are using a real testing weapon.

The firing pin of this weapon is extremely quick and we have registered the pin to hit the button (A button) and retracted within 1/100th of a second.

We are experiencing a non-consisting registration of the fire and we are wondering if it might be because of the high velocity of the press.

Do you know what the sample-rate for the button press?

Do you know if there is a buffer for input?
