I've seen a few people get 122%, but at this point I'm convinced it's not something that realistically be obtained unless you have just a lot of luck.

Simply put, you need to basically average something like 60ms of delay in your reaction time when hitting notes, and you need to do this reliably, because just a few notes below that threshold and you won't get 122%, and even if you get ALL cyan "Exact" ratings, you'll still likely not get 122%, because you need some VERY specific reactions.

I've played GAMEBOY 17 consecutive times trying to obtain the 122% achievement, my best was 121,918%, and I generally averaged above 121%, but getting to that sacred number for the achievement seems to be outright impossible, and consider that I'm using a decent keyboard on a 75hz Freesync monitor with Radeon Anti-Lag on, so basically my reaction time is as best as it can humanly be, and even then, it seems impossible to reliably hit notes within a decent margin to guarantee you get 122%, it seems like all you can do is hyperfocus and hope you get lucky enough.

Any tips? At all?
