in niftski 454.798 the timer said .81 how can he calculate it

in 8 4 il pellson rom said 42.50 but it says 42.27 on leaderboards i want to know how to calculate both

u need to use somewes.com to get the exact time, it also depends on where u grab the axe. at somewes.com u can figure it out u just need an approximate time

also mods can retime it themselves so u really dont have to do it, its completely ur wish

Thx
