Might be a 4:28? Not sure which exact frame I'm supposed to split. I had one drop on Trial 16 that cost 2.2 seconds, but other than that this was almost perfect. 4:25 is probably the limit without a new discovery.

For this run I optimized a few strats, avoiding slow Red Focus combos and not wasting time with unnecessary dashes. Notably, I saved some time by using FADC at the end of EX Lynx Tail, which lets me juggle DP faster (and allows me to do 2LP 2LP 5LK xx EX Lynx on Trial 22, making that WAY easier). On Trial 24, using 4 forward dashes is ~0.65 seconds faster than my previous strat of HP Mallet into LK DP xx Red Focus, but involves a 2f link instead of 4f.
