Wow, grats! That is the best I've ever heard of someone doing!
Just experimenting now, here's a bit on it now:
If you have Sonic jump at an angle that's curved a bit above a straight right jump, you can get a bit of length; and also (if you use your air dash right)can get up quite high above the ground.
If you jump in a 45 degree angle, you can go quite a bit further, just tried that now to have the blue guy land at the 34617M mark

.
Straight up just sends you up at a 45 degree angle.
That should help with getting further.
