i cant seem to consistantly kill the first ksec guard like other speedruns. i mostly just get a mission fail even though I go around him 2 times both ways. i still seem to get a fail. what should i do

Ive been wondering whats the best way to become a mod, or what i need to do in order to become a mod <3

So, ive been playing this game since last september, but ive more recently just started to speedrun it, are there any tips you all could give me? im already using taps, low sens, but i feel like Im not going as fast as i can. thats just one of my issues.
