Week 3 OPR - All regionals/district and World ranking

[Ether]

If there's any interest, here's the Twitter data (all data; no macros, no formulas) for Qual and Elim matches for weeks 1, 2, and 3... possibly useful for locating highest-scoring matches and other such things of interest.

Subject to caveats discussed elsewhere (missing data and some foul points not correctly recorded).

Thanks Ether, great job! I wanted more parameters to use so I decided to look to twitter feed over usfirst match results to get my data. How were you able to parse the twitter feed? As in how were you able to extract using the XML out of the twitter pages?

I didn't mean to hijack Ed's thread. Take a look at these two threads:

... and if you still have questions post over there and we can talk ok?

Good to see some of the Week 2 performances held up quite well to the onslaught from Week 3 teams.

Liking the inclusion of CP influence into the overall calculations.

Thanks again, Ed!

Inclusion of CP a good idea but not sure it is enough as formulated to compensate for the amount of TP lost during final 45 to 60 seconds almost every match for our team on the Co op bridge as we focused more on guaranteeing first seed than racking up points.

I haven't been able to open Ed's spreadsheet, but from what I've read I assume he has reported each Team's least-squares calculated contribution to Hybrid, Bridge, TeleOp, and CP separately so that the user can blend them any way he deems most appropriate.

The Jumbotrons in VCU did a great job of sucking some OPRs dry.
We aim to please in Raleigh.

This is more or less impossible to do without any data on what was the average time left in the match when that specific team started to balance the Coop Bridge, as I'm sure this value will vary from team to team. Some teams may play it safe and start to balance much sooner, while others may push their luck.

Even for the same team, I would expect this time to vary from event to event based upon the average match difficulty (among other variables). Teams at weaker events will likely start balancing the bridge sooner to ensure that teams with weak bridge tippers and/or weak/slow drivetrains can make it onto the bridge, while teams at stronger events will likely spend more time scoring during Teleop to both help secure a win and because of a higher confidence that a balanced bridge can happen in a shorter time span.

You get 10 bridge points for balancing on the coop bridge which is the same if you were to go to the alliance bridge to balance on your own or with a partner. I think this is Bongle's reasoning to choose to do it this way.

Ether, I added columns to show adjusted OPR bridge points and overall OPR and use that for ranking purpose. Teams can change the number of points for each Coop bridge point but the ranking will not be recalculated. I am still trying to write out in .xls format but without any luck so far.

My reasoning was that the 2 CP points earned by each alliance could have been 10 bridge points for each alliance if their alliance members had decided to go for the alliance bridges instead of the CP bridge.

Really, I should've just left the adjustment only in the bridge category rather than also including it in the overall OPR as well. But several sets of stats had already been posted, and removing it would make week-against-week comparisons difficult. The reasoning for including it in overall OPR was that teams who were on the CP bridge every match rather than the alliance bridges would rank very low in the "prestigious" overall OPR, even though they could've ranked quite high if only they'd balanced a different bridge.

I failed- accidently looked up 1620 by accident. Just noticed that now.

Thanks.
