Just enter in an event code (for example "onto2" for Greater Toronto Central) and it will output component OPRs and an "adjusted overall OPR".
See post #5 for instructions on getting event codes.
The adjusted OPR value is like the OPR you would find on the blue alliance, except it's calculated without foul or coopertition points.
Click on the column title to sort the data. If you want to store a local copy, clicking "download" will download a CSV file containing the calculations (the csv will match how you're currently sorting the data).
Overall contribution is another metric that approximates the percentage of points a team contributed to their matches on average.
We might add special cases for surrogates later, so for now this data is slightly less robust than Ed Law's but should still prove useful.
Let us know if you find any bugs, or have any suggestions.
