This category is really weird. You'd think that falling through the platforms at the start would save a lot of time, but because the rail underneath you is sloping downwards, you fall for longer before you can land on it and start accelerating, and you also build up less speed since you land on it further to the right. I think the optimal strat (which I ended up doing here by accident) is to long jump as soon as you land on the row of platforms, then get the one you missed from the side while falling through the first block. Because I did this on accident, I long jumped really late, so this run is extremely beatable but I do not want to play this level anymore.
