if you want to send a chart for a song that's already claimed, feel free to do so
if the chart isn't different enough than the first chart, I'll use the first one. if it's varied enough, I'll use it and change difficulties accordingly

also, for songs that have multiple charts, which charts I keep ultimately depend on the song. hit and slap will most likely retain just the hardest chart, tamayura will most likely retain beginner and challenge, etc.

edit: I'm not endorsing sniping, but if someone snipes someone else, I'll have to resort to using the "better" chart
