Thank you. I'm glad to see people are benefitting from it.

As a sidenote, thank you to FRC HQ for making this data more available for capture. The API certainly provides much better data than the twitter feed over recent years.

Agreed. Also thanks to Ether and team 2834, I have built off of both of their work, and this spreadsheet would not be possible without them.

I have some questions about the "units" of some columns... I'm pretty sure they're my initial guess for most of them, but I wanted to double-check.

For columns H and I (teleop Capture or Breach), I presume a "1" would indicate a successful Capture/Breach?

For columns J - V and AM (defense crossings), is "1" a single defense traversal (5 pts) or a weakened defense (10 pts, 2 traversals)?

Also, how are eOPR 1 and eOPR 2 calculated? What's the difference? They differ dramatically from the OPRs based solely on match scores.

The "instructions" tab has more detailed descriptions about each category, let me know if anything there is unclear and I can revise it. I'll summarize here anyway though.

"teleop Tower Captured" and "teleop Defenses Breached" both have units of ranking points. A 1 in either of these would indicate that the given team contributes an average of 1 ranking point each match.

All categories that have "crossings" in their name have units of crossings, not weakenings. That is, a 2 in any of these categories would indicate that the given team contributed 2 scored CROSSINGS over this defense each match.

eOPR1 and eOPR2 are my rough attempts to compensate for different scoring methods in quals and elims. Since breaches and captures provide points in elims, but not in quals, "normal" OPR probably does a poor job predicting elimination match scores (although this is as of yet unverified). eOPR1 essentially makes boulders and crosses scored in quals worth more, and eOPR2 takes breaching/capturing contributions and assigns them point values, and then adds those to the "normal" OPR.
