With all this talk about the Overpowered Mode I decided to test it out. Normally I would start on wave 441 and gain time just like everyone else maxing to what you saw above. I just started this OP run from wave 11 with starting gold at 78/200, it took about 9 min to get to wave 656, which is when I lost OP. During that time I banked 31:30 min of ability time. This is 11 min more than I earned last night playing from 441 - 1876 which took a few hours in just a few min. Will this payout in the long run, I will keep you posted.
