yes, i thought the level was long then i realised it can be some in (for me 38) seconds, so ill be focusing on the 100% category, im about to submit a 1:33, and I think i have a good route, not sure though.

I think 17-2 has lots and lots of potential to be optimised, im about to post my current strategy for the level in 'Guides', I got a 2:21 with it but that was with sloppy movement, I would really like to see everyone try and reduce this as much as possible

Im really not sure, I have looked for a while now and can find nothing, all I can think of is minimising propeller time, and im working on some method to triple jump to skip some of the jumps after the blue platforms However I just realised how fast you can go using the conveyor , thats the way to go
