I'm having a really hard time getting the game to lag every time so i wasn't able to finish a run yet... BUT! When i do get it, i'm able to get 23-24 point every time thanks to something no one aparently seem to do in the run i saw. so i made a little video on how to do it, and save some time on run:

Hope this help!

Pretty neat strat, if it works for you. However, it might not be always better. I know for myself that it would not be faster since i am able to click very fast with my right index finger, that's why i'd stick to my own strats. On top of that, the duration of the freezes depends on your PC. If you have a fast PC, the lag spots are shorter and because of that you cannot achieve as many points during one freeze. On my old PC my personal record for points in one freeze was 29, but now i'm kinda happy when i get to the 21-23 mark.
