This site allows you to paste the chat log from your X-Wing Vassal games in order to get some statistics about how 'lucky' you were.
It originally began as an idea of current X-Wing world champion Paul Heaver - a command line application that, when fed the cut-and-paste contents of a Vassal X-Wing game, would spit out some basic counts: total dice rolled, number of hits, number of crits, etc. I took Paul's basic idea and implemented it as a web site. You can find/fork/contribute to this site on github if you'd like to help out with its continuing development.
If you want to read more about the app, head over to The Team Covenant site, where I'm managing communication for the app.
