This seems like the correct forum to post this, but mods feel free to move if not.
I'm going pro in about a month, so I wanted to write something that could tell me what kind of swings I could expect based on my past play, so I came up with this:
https://github.com/snex/poker_tools
It gives data about expected swings, as well as gives some simple moving averages with win rates. Comments, suggestions, bug reports, interesting looking results, are all welcome.
