Early 100% routing. So far the most stressful level to try and 100%, we'll see if Factory tops it.

• Hope you don't accidentally lose wings
• Any movement other than just jumping on the very first boost 9/10 times keeps you from acting afterwards and idk why, just jumping lets you dive to the first trash
• Not sure if burning the first wing to get to the higher boxes faster is better or holding onto it to jump immediately off the pipe to the closest tower after that section is better
• If you do lose wings, you can go to the O section, grab the 2nd lowest, then make sure you get the lowest and one on the box below (depending when lost you can use the lower to get the 2nd and drop back down or just climb back up to get the lowest one after); didn't test but messing around on that right section it's likely still faster than dealing with that mess
• Also untested but it may be possible to manipulate movement off of the return shroom to land on the R pipe; saving wings is almost certainly quicker unless burning the excess you can easily save just helps that much, doubtful though
