FiM 2016 Southfield Game analysis using Team 2834 spreadsheet

[Caleb Sykes]

Can someone please explain EPR to me again. I seem to recall it being short for "Ether Power Ranking," but that's about the extent of my knowledge of it, and I can't seem to find the original thread where it was conceived.

It's just something I tossed into the mix to liven up the discussion in a thread exploring various alternative metrics.

Okay, it's coming back to me now. EPR is calculated like a midpoint between OPR and WMPR, but it can be interpreted in the same way as OPR is interpreted.

I still don't understand what "Avg EPR" refers to in the new 2834 database or in this post, or why the OP is using EPR as a measure for the difficulty of a given match schedule.

In my view, the aggregate qualification data is only useful for the top 3 teams. The noise from random pairings swamps any conclusions you could draw from the FIRST feed.

Does the analysis make any allowance for bonus ranking points for breaches and captures? That might help explain a couple of apparently anomalous outcomes. I think 247 may have contributed to more breaches than the lower finishing teams. We certainly intended to, although the difference between the real obstacles and the practice obstacles had a huge effect on us. It wasn't just the bendy drawbridge and sally port. The loss of friction on plastic was something we just didn't see coming. Our bad, and fix it for next time, but we still drew down the drawbridge and opened the sally port by ourselves, which I don't know if any other team did. That added a couple of extra breaches to our totals.


....Or maybe we just got lucky.

Thanks for the kind words about 1025. It took us a bit to get all the bugs out and figure out how we should be playing the game. We're looking forward to our second competition and states.

We had the same issues with the floppy drawbridge. Our "big arm" was designed to pull it down. It works really well on the team version. We tried it out on the practice field on Thursday night. It was much more difficult to do on the real version. It's a lot floppier, and the drawbridge being two layers of polycarb also didn't help. We found that we would occasionally grab just one of the layers. Thus we decided to not even attempt the drawbridge from the front in a match. Maybe in Marysville...

Team 4680 had the highest Defense Score, and by using FRC spyder Event Stat for Max Defensive Crossing Score it was second highest for all Week 1 competitions (not counting Israel) That made our driver feel good.
