well, the sept CTTH sweeps have all been "finalized"...i posted a sub 95 in all of them, and my CTTH average score didn't budge and remains an eye popping 331, as it has been for over 6 weeks.
so i've come to the conclusion that CTTH average score is your worst
10 in your last 1000 challenges (lol)...this makes sense as i posted a 700+ in my 1st challenge on my 1st day.
