Offensive Power Rankings for 2008

[cziggy343]

i think we now know why its no wonder that whenever 1114 and 2056 got together, there were a lot of points scored

OPR of teams going to the championship event. Qualifying matches at all regionals.
Go check out Travis Hoffman's post a few down, he added position numbers to my more-raw post.

Beware that this post includes all of a team's matches all season. 1114's OPR steadily increased from MW to GTR, and ended up at 80+ at GTR. I'm sure most multi-regional teams did as well.

Since teams such as 1114 are not going to back down to their older OPR's can you post one that only includes the last regional of each team.
I know it could be challenging to set up the program, but it would be a great tool

Thank You

Alright, I have thought of a way to do that without too much pain. I should have it done in an hour or so.

You have the Israel teams.

It looks like you are missing 858, 1254, 2335, 2337, and 2604. Looks like 4 of them all went to West Michigan.

West michigan has funnily-formatted results on usfirst.org, and I haven't adopted mine to run on TBA CSV dumps. That's my guess. It's in my list of regionals, but even these updated ones don't include those teams.

Anywho, find attached an XLS file detailing:
-A team's regional count* (I may have missed some regionals due to formatting funniness)
-A team's last OPR
-A team's last regional
-A team's best OPR (if it differed from their last, which didn't happen much)
-A team's best regional

Note that some regionals still don't have all their results up, so for those regionals (Peachtree and one other) the OPR will not be 'accurate'.

oprChamps has only teams attending championships.
oprAll has all teams.

Even if you don't use TBA CSV dumps, the data on TBA is formatted very cleanly in HTML tables that ought to copy-paste well into Excel or what have you to turn into good data.

You make a good point.

Now includes western michigan regional. oprChamps now includes 333 teams, just like it should.

There seems to be a massive discrepancy in the the championship OPR you posted early today and this one. For example, in the first on our team (573) had a OPR of 22.3 and ranked 88th. This one the OPR is 20.2 and we rank 125th. Would you care explaining this discrepancy to me?

Which regionals did you attend?

Edit: I have discovered you attended pittsburgh and glr, and here is my theory:
-The new listing only ranks you based on your performance per-regional. The old listing was based on a team's total performance over all of its matches throughout the season. Through the magic of mathematics, your team looked a little better when the overall performance of every team was factored in.

So just like teams like 1114 who improved massively regional to regional get a big boost in the new listing, other teams can actually suffer. Although keep in mind that according to the best OPR listing, you're 115th, because your performance at pittsburgh was better than that at GLR.

Pittsburgh and GLR. You did point out the difference in the two OPRs (Pitt was 21.6 and GLR was 20.2) But that still doesn't add up. And apparently while our numbers went down, other teams went up from what they were.

Yeah, teams going up is to be expected. Think of a team like 1114, who steadily (and massively) improved their performance from regional to regional. This most-recent listing is ranked by a team's last regional performance, which is very often their best regional performance. A team that did very well at their last competition but poorer earlier would have ranked below you in the earlier rankings (which were based on the whole field of robots at once), but would be ahead of you in these rankings, because these are ranked off of a team's last regional performance, like people requested.

I like the new OPR of the last regional attended, due to the fact that it is more indicative of a team after adjustments to driving, strategy and robot features were made after attending more than 1 regional.
Our biggest feature change was moving our pneumatic piston to our claw which pops balls over the overpass once our claw opens.
We sacrificed popping balls during hybrid and moved it to our claw instead.
With increased speed, hybrid adjustments, and improved driving, we went from doing 1 or no lines in hybrid to now being able to consistently doing 4, with much greater speed, and hurdling capability.
Its too bad it took 3 regionals to figure it out, but at least we will be much better prepared for CMP.
On another note, its funny how us and our favorite Hawaiian teammate are ranked next to each other, off by a few decimal points.

I just got an interesting idea.

I have scouting data for matches from Friday at the Wisconsin Regional for every team. However, the power rankings are for every match.

Could someone please figure out the power rankings using only Friday's Wisconsin matches for comparison?
