I summed up the best times between your glitched run and my glitched/glitchless runs and I got a time of 47.96, which means that is theoretically possible for a glitchless run and something you could aim for.

I actually managed to get a 2.9, I was going to hold out on giving it away since I might have done the glitched runs myself but it's more tedious then I though so I'll tell you anyway.
There is a bug in the game that if you get pushed into a block by a moving platform as a ghost it glitches you through, if it glitches you into a long line of blocks (like on level 11) it will almost instantly launch you up the distance, so using this you can launch straight into the finish.
