The hard part isn't even turning them into useful numbers. The hard parts are: Making sense of what the things in the log files actually mean. It is NOT always intuitive. Supporting multiple log file formats Correcting things when EQ makes mistakes (bad timestamps / errors) Making the UI to show the numbers in an easy to understand way. I actually added a simple version of that functionality already, it just doesn't have ui elements to enable it yet. What I never finished was figuring out how best to illustrate which lines were actual matches vs the before and after. My first thought was simply coloring the lines, but that doesn't always help, it seems a lot of people that play EQ are colorblind, heh.
