Nvm, trust me, it won't ban you if you are pro, or just had a big luck. And yes, there is cool-down ofc.
Player camera has 2 values: xy(0 - 2PI)"around" and z(-PI/2 - PI/2)"up-down". SAPP checks the change of these values 100 times/sec. Snap is sqrt((xy_change*(180/PI))^2 + (z_change*(180/PI))^2)° =)
