halo infinite sensitivity is completely off. For example try Valorant conversion. It puts 1.5 sens on Infinite to 1.1 in Valorant.

This is about 3 times faster than it should be.

You might be experiencing the acceleration issue as demonstrated here:

 I run the same script to do a 360 four times. First time it's accelerated, second time it works correctly, third is accelerated and fourth works again.
