I thought it was time I made a contribution. This is a fun spreadsheet I put together for my own benefit. I used the F+ ratings from 2005 to current to evaluate conferences against each other. You pick the two conferences and two years and the spreadsheet does the rest.
Again, this is just for fun but I thought others would enjoy it. I'm sure there are a few kinks I haven't discovered. There are several hidden cells but I didn't lock them...feel free to peak behind the scenes.
I welcome any questions or comments.
