I can't believe it! I had found something in Yellow that made it so you wouldn't have 152 pokemon, but I had totally forgotten until today. I didn't realize that there would be 3 swaps (which wastes a little more time) to get:
1. a rating that doesn't require an button press to clear, and
2. less lag for click items in battle.
This is the last improvement with these strategies, for sure. As a reminder, this is not meant to beat any records, just to show something I had discovered a while back... and do that part as fast as possible.
