I tried to turn the sound off to see if it was any more likely that I could get a 53:66 again, but so far no luck. I was just talking to a computer geek friend of mine, and he says computers have 2 clocks, interrupt driven, and real time. The interrupt driven clock is supposed to be more accurate than a real time clock, but the processing time depends on the number of higher priority interrupts, so either way there could be error, but if the game is using an interrupt driven clock that could explain why different game settings might influence the time. I wonder if just having the Wii console connected to the Internet for tournament competition might also make faster times less likely. I don't think it would be that uncommon to want to turn off the annoying background or walking Mii, yet almost everyone has been getting the 53:68 time. I wonder what backgrounds people use that get the 53:69/53:70 times.
