Got the hang of the blue MT right before the ramp, after the shroomspot, which helps a lot.
Just got a pretty decent run based on my best times, but still not 100%. Plus I still need to somehow work in the orange MT at the end of the first two laps, but I'm terrible at it.
rMMM: 1:28.356 - 30.518 - 29.211 - 28.627
Would be #22 on the site, which is my highest so far

Glad if I decide to focus on a track that I can at least do decently well.
Edit: I was having a really hard time getting close to my PR again, but then I got this...
1:28.412 - 30.450 - 29.292 - 28.670
I did manage to get a 30.2xx first lap one time, so I guess there's that.
