That was 135 new threads in 7 minutes short of 24 hours, based on your last post.
So....
834/135= 6.185185....
.185185 x24 (hours in a day) = 4 hours, ~26 minutes.
So we get ~6 days, 4 hours, 26 min.
Given you must pick a full hour, and 26 is < 30 , it is closer to 6 days, 4 hours than 6 days 5 hours.
HOWEVER: note that this is just a mathematical estimate, as thread creations, I am sure, are not linear, so this is JUST an estimate based on 'one point in time' data set.
