Several of the current records on the target test leaderboard are from outdated versions (namely, 4.0bc) see Jigglypuff, Ness and others. These should be purged from the board since a lot of these routes are no longer doable due to changes to characters (Ness shine no longer hits the target through the floor, Puff's sing has a greatly reduced radius, etc.)

yeah, absolutely. it's been a while and the game has changed quite a bit since then.

I'm down for removing records of old versions if others are. Is there a consistent way to tell from the replay alone which ones are from BC (or even 4.1?)

most of the old replays (from 2 years ago) are from 4.0bc, so it's probably a time tell from when a replay comes from. some videos also have the version in the title, so that's another way
