I had trouble at first because of my lack of consistency. But since then i learned how to do the shortcut with a shroom and now i can do it 95% of the time shroomless. If you practice you can probably beat it. Its a hard track to finish a run though as i can get splits like 50.5 but my PR is 2:34 :(
I got 2:47:660 as a noob, and for a while I did nothing to beat it, then when I finally tried it again I couldn't pull off the WR strat, so I was stuck with that time for a while!
