The final 2014-15 ratings are now posted. There are some ideas that I plan on coming back to over the next weeks/months, but for now I post them without much of any commentary except some logistical notes about procedures:
1. I made the decision to include a broader range of tournaments than I had previously. The cutoff for tournament size had been approximately 20 teams. I expanded it to include tournaments that had as few as about 10 teams. It is important to remember that not all rounds from each tournament are included. In a previous post, I explained how eigenvector centralities are used to determine which teams' results will be calculated. In short, if either team in a round has an EV value of less than 0.15, then the result of that round will not be counted. So while the results from a small tournament like West Virginia are included, about half of the rounds are not counted because many of the participating teams lack enough reliable data to produce a rating.
2. Because of the inclusion of a broader set of tournaments, which in turn influenced every team's EV values, there is some small discrepancy between how the newest ratings calculate the regular season (pre-districts) ratings versus the ratings that I actually posted after Texas. The difference is small, but could influence rankings where the margin between teams was also small. This only matters if you're looking at the "Previous" or "Change" elements of the table.
3. The D8 tournament was excluded from the data set because I haven't yet had time to figure out what to do with 2 judge panels.
