everything below is what i originally got and wrote, after that text - i got 181 on average and recorded it on a video to show that i'm legit and not like many others here with their random clicks/prediction clicks..

/////////////
got 183 after around 10 minutes of trying, key was to not get more than one 190+
anyways, rusty now, long ago done ~167ish stable on that website, also everyone must know that unless person really trained hard in that - he can't do such ms, i personally trained hard long ago exactly in click on the green/sound/image, for months , minimum human can do without random/prediction clicking on that website is around 150 due to little to no input lag compared to a game, inside a game i'll say up to 170ish max (i personally done 0.192 inside one.)
other info:
remember that such website and games with similar tasks require mainly lowest input lag possible, that applies to both your monitor and mouse/keyboard , Hz of the monitor is a secondary thing, and yes, mouse and keyboard have their own input lag too
