I've sent an Test Stage run with 5:22, but when i compared side-by-side with the actual wr (TommyeAsY), i've noted he was faster than me. So i played more and got another faster time (5:29) and this time was the real fastest.

Comparison side-by-side with a timer

If you see the timer turning a 1 second, he goes from 0:37 to 1:41 and the miliseconds is not synced with the seconds.

My faster time was 5:04 TommyeAsY got 5:25 My another time was 5:55
