TL;DR: Practice and Scroll Wheel
for bhop just in console do:
bind mwheeldown +jump
Every time you scroll down you will jump, making it 10x easier to bhop.
Technical Stuff Below (This assumes you know how to airstrafe also you don't have to read if u don't care)
[First, your perf chance is not increased on 64TICK OR 128TICK but your strafe gain is on 128.]
Perf = Perfect BHOP (GAIN SPEED)
Perfs are semi-luck based in the sense that hitting them requires to get the 1 tick timer(75ms) that counts as a perf or not.
Most players then have a internal rhythm they follow. Not in sense of counting in their head but more a muscle memory thing.

(128Tick) An example here is that I follow a rhythm about an average of 10 scroll inputs per bhop.
View attachment 2003
(128Tick) This player follows a rhythm about 7 scroll inputs per bhop.
So it's about
practice.
You'll get your own rhythm eventually
