What is PowerScore?
Put simply, PowerScore is a statistical analysis run against the qualification match scores from FTC tournaments. The goal of the PowerScore analysis to find the teams who have been more effective at playing offense in the FTC game. As opposed to the team ranking used by FIRST, PowerScores are only interested in finding those teams who have been particularly effective at scoring in the FTC Game, regardless of wins/losses.
PowerScore is designed to be used live during qualification rounds at a tournament as well as a tool for post tournament analysis of team performance. It's suitable for use at all tournament types - meets, qualifiers, super-regionals, and even the world championship.
The design of the PowerScore calculation lends itself well to use during live tournaments, especially during early rounds when data is severely limited. It's similar to the Offensive Power Rating used commonly in FRC and somewhat in FTC. One advantage of PowerScore is that it can be used in early rounds, and can benefit from pre-tournament scouting.
Can Other Teams Use PowerScore?

Latest Release (V4)
New in the Fall of 2017, V4 is now finally released. We've included many improvements and fixes. This release features ann entirely new way of calculating that is both more efficient and lends itself to some cool visualizations. All of the summary pages have new features, including the ability to view and sort by multiple statistics. "Alliances" gives a way to understand how alliance powerscores work out, and can possibly help when looking at selection scenarios. Introduced the experimental "x-factor" stat (which is really just a deviation measurement) to help identify teams who have high consistency in match performance.
See the instructions on the spreadsheet for more information.
