OK, lets give this a shot. Linked below is a spreadsheet with some very basic statistical formulas, and every show in 2013 listed in the first column.

1. Open spreadsheet
2. Choose an empty column
3. Enter your username in row 1
4. Rate each show from 0 (fire-least) to 10 (firemost), with 5 being the median show for 2013. Which is a really good show. (The overall average for everyone included in the piece above was a little over 6.)
5. Decimals are fine. Non-numerical entries are not.
6. Please don't mess with the formatting, formula cells, re-sort rows, etc. If you see something you want to change, please PM me. If you want to take a copy of the sheet to play with, by all means, do so. This lasted less than 2 hrs among a very small audience in the forum; maybe we can top that here and get a large sample size that includes deaf n00bs and deaf jaded vets alike.

There are about 50 columns available. If/when they fill up, I can add more.
You don't have to rate everything at once, but is you start a column, please commit to rating every show. (It took me about 2 days.) It doesn't really help the effort if you just drop 10's into the 4 shows you hit this year.

Have at it:
