Finally broke 500K on my first Team Trial attempt of the new session. I didn't think it was possible with my current team since I still had a few B+ Umas on it. It turns out the secret is to just get matched up against someone who has no idea what they are doing.

Like holy shit, his team was so bad despite everyone being A or A+. Over half of his umas had Iron Will, and a lot of them had skills for the wrong distances. Cap and Condor were in dirt as usual, but had B aptitude, and Haru was on sprint with E Turf for some reason.
