I saw m1 a month or two ago, it is an excellent run, I wonder how many people realize how much harder it is to play on DC cause the controls are so messed up, when you hold UP it does not usually go straight up like on GC, you kind of zigzag easily and it is ridiculously hard to go in a perfectly straight line, which is effortless on GC, but very important in most sonic levels.
mission 3 can go to 51 like you said, but it is still good and you took it lower than I expected with your superior little route touchups I did not know about.
and you better not be 'stopped' in setting new times for long, cause you have a lot of potential that needs to be unleashed! you could take every sonic record...maybe more than that
