My movement could be slightly more optimal but I generally took the safe route to avoid whiffing anything. The only tiny mistake I made was on Trial 17, doing dash straight instead of dash Super, but it barely cost any time. This was a hard WR to beat since it was so optimized already, I'd guess there's only ~3 seconds max that could be saved with current strats.

The U1 juggle on Trial 5 can actually be done without switching sides, but it does more hits at the end. It ends up being almost exactly the same speed regardless of which side you choose, so I picked the one I'm more comfortable with execution-wise.
