2014 District Point Model Analysis
 
Main Reference: 2014 Projected District Point System

Below are some VERY interesting graphs and stats from the 2/6/14 PNW District Webinar (Video):




^This graph was the most interesting. I'm currently working on a further analysis including the other newer district regions: MAR, NE and our friends in Canada :)

The Pacific NW webinar and these graphs inspired me to take my old model and apply the new point system and include average OPR:

*Teams underlined were Chairman Winners.


I graphed Teams and sorted by Rank, showing Points vs. OPR:


*I realize there is a lot of statistical noise. I also didn’t normalize the events.

With all of this in mind:

64 teams would qualify for the District Championship. 10 district Chairman winners, 54 taken from the point system ranking.

Points accrued at the District Championship are worth (3x) as much.
PNW would then send the following (24) teams to the World Championship:
-3 Winning Alliance Members
-3 Chairman’s Winners
-1 Engineering Inspiration
-1 Rookie All Star
-16 Teams based off of the District Point Ranking.

I love the fact that last year, our 156 teams made up slightly more than 6% of the 2509 world team count. This means that we would have filled 6% of the 400 Champ slots.

I really hope that when we are in an entirely unified District System that Regions get a percentage of slots based upon their relative size.

Along with the further analysis of regional representation, I am going to create a 2014 PNW District Point Database here.

I'm super excited for the new District System to play out in the PNW. Good luck teams!

Where was the raw data for the first graph obtained? Is there somewhere where it's already compiled, or was it mined by an individual? How far back does it extend?

I would like to know myself, I just shot Kevin a message on Facebook. If I can't obtain it, I plan on mining what I need myself to expand on graph 3.

My theory would be Zondag's spreadsheet would have most of this data.

Being on the District Championship winning alliance does not earn you an automatic spot at World Championship. It is highly likely that you will earn a spot with the points that you earn from being on the winning alliance, but it could be possible that the 2nd pick doesn't make the cut. This is done to give those teams from the Valleys of Doom a better chance of moving on and tries to minimize the chances of that 16th pick getting a ride on the coat tails of the #1 seed.

Yes the data for the first graph is from data presented by FiM.

Re: 2014 District Point Model Analysis
 
Its interesting, but these graphs don't really show anything that anyone couldn't automatically tell you. #1 and #2 alliances are the strongest, and overreward 15th and 16th picks compared to their OPR.

The district model does a better job of ensuring the best robots go to CMP, and consequently, Michigan representation in CMP elims is more indicative of their size in the league.

This is incorrect. Winning District Championship does give you a bid to Champs. Those teams are then 'eliminated' in regards to looking at standings for the points-based slots.

Re: 2014 District Point Model Analysis
 
Very cool graphs! Comparing the first two graphs is definitely very cool... it really does show how much of an improvement the district system should make in sending good robots onward!

Actually they told us in the last district meeting that winning the Championship does NOT get you an automatic bid to worlds. I don't really understand it, but if that's what they decided then that's what they decided.

It's not automatic but the points involved typical result in it? /speculation

Re: 2014 District Point Model Analysis
 
That's correct. There is no automatic bid- but if you think about it, a winning team would be (assuming no backup bots) 30 points for winning multiplied by 3 for being a district championship. That's 90 points, which should be plenty to put that team in a good position to advance regardless.

Re: 2014 District Point Model Analysis
 
At least for New England, the winners at DCMP will move on to CMP automatically, as mentioned at the bottom of this link... http://www.nefirst.org/2014/02/04/ne...structure-faq/

I'm not sure if this is a global FIRST decision or an NEFIRST decision... I don't think it is mentioned in either this blog post (http://www.usfirst.org/roboticsprogr...Kickoff-Taping) or the official points supplement (http://www3.usfirst.org/sites/defaul...ng_System.pdf).

For the lower seeds (5-8), it helps all 3 qualify. If you are the 3rd pick on a 1-4 alliance, that might not get enough points for you to make it, because if you face a 5-8 seed in the finals, all 3 of those bots will have more points then a 13-16th picked bot.

I will say this most likely won't happen, but if a team this year wins the championship but does not make it to worlds on points, I think there will be a huge outrage, and I will fight to make it so the winners make it to worlds, because thats how it should be no matter what.

This is the way I understand it - but I'm checking in on this. Thanks for the patience!
