FiM 2016 Southfield Game analysis using Team 2834 spreadsheet

[marccenter]

Dear CD,

I have downloaded the "new" Team 2834 scouting spreadsheet and analyzed the data from the FRC2016 Southfield FiM district event. Here ARE my observations (oh, by the way, Team 3548 was part of the winning alliance with alliance captain #1 3604, the Goon Squad, and our sister team, 1188, from Royal Oak). My observations are based on the data only.

1) Using the new EPR rank, FRC Team 3548 benefited from an easier schedule (10 =3 = +7 EPR) to establish it's #3 overall ranking. BTW, we had a solid breaching robot, fully auton capable from our first match and a solid low ball scorer. We created what we thought would be an excellent partner in a alliance using a minimum competitive concept robot.

2) Team 1025, IMPI's, distant cousins to Royal Oak and District Chairman's, had a tough schedule and ended up ranking only 13. If we had changed schedules you guys most likely would have been District Chairmans and Champs. Keep up the good work and you should look forward to your next FiM event with your head's held high!

3) Team 5756 had the toughest schedule of everyone compared to their EPR ranking. The FRC scheduling god's dumped a load of boulders on you. Don't give up. You should do well at your next district event with a little scheduling luck.

4) Team 247 benefited tremendously (36 - 16 = EPR +20) from their easy schedule landing in number 16 place. The FRC scheduling god's really took care of you guys this time. You may not be so lucky next time.

5) Other team's with relatively tough schedules and/or bad luck during matches included teams 4327, 5915, 5478 and 4768. Keep on persevering and goods things with happen soon!

P.S. A man who know's his numbers is a man you can count on!

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.
