Nothing to report, Stage 4 is identical to Team 4's run. Curiously, whatever changed in prior stages, it all lined up the 32-frame rule and item drops happen exactly as before.
This is in case no one wants to mess around with trying to copy in some team's run. Team 4 is the fastest, though not by a wide margin, and there may be some strategies to mix in from others. I'll make a more detailed post thinking about each team's efforts soon.
