I’m not sure why you’re having difficulty with your anicancel test but… The attack speed boost for someone under 100 ping is huge, RS or not.
As an added note, anicancel with kneeling shot does not work for me, only the standard attack/move around with mouse while shooting target. Thus kneeling shot 5 is pretty underwhelming in terms of its “attack speed boost”.
The anicancel boost without RS (As I’m not a QS) is big enough that I shoot like I’m using r5 kneeling shot, but I’m not. (I did not record hits, this is an approximation.)
Edit: And yes, the anicancel is VERY consistent, I could never go back to using Z to attack, it’s just that much slower.
I play on Klaipeda if you’d like to do some tests in-game when I get home from work.
