Re: 2013 NE FIRST District Rankings
I agree with the logic on making the third pick worth just as many points. The serpentine in particular makes this problematic - I would hate to be the 8th seed and have to pull up on my phone which team "needs" the 1st round pick points more and which team doesn't.

Although I suspect these points were removed in NE's proposal because it makes things a bit more complicated, I think assigning points based on alliance selection order as FiM and MAR do (16 to first 2 bots on Alliance 1; 15 to first 2 bots on Alliance 2; 14 to first 2 bots on Alliance 3... and 8 points to 3rd robot on Alliance 8, 7 points to 3rd robot on Alliance 7, 6 points to 3rd robot on Alliance 6) is the best way to assign points for eliminations (in addition to points based on finish). Using 2013 GSR and 2013 Pine Tree as case studies (I chose these two because they're Week 1 vs Week 6, vary significantly in size, and Pine Tree is interesting because the red alliance won each matchup): GSR Pick Order & Results: 610-4124-3609... WGSR Points (based on current NE proposal) 30-30-30... WGSR Points (NE proposal + alliance selection points) 46-46-31... WPine Tree Pick Order & Results: 2648-3467-2386... WPine Tree Points (based on current NE proposal) 30-30-30... WPine Tree Points (NE proposal + alliance selection points) 46-46-31... WSeems like the current NE Proposal has several weaknesses: - 1st and 2nd robots of each alliance get same reward as 3rd robot. - Winners get 6x the points that the quarterfinalists get (3x the semifinalists). - 1st and 2nd robots of finalist alliance (theoretically 3rd and 4th best teams) get 66% the points of the 3rd robot of the winning alliance (theoretically lower than 20th in ranking of teams). These particular issues are improved with the inclusion of the alliance selection points. It'd be interesting to also add in the win-loss information... but I don't really have the time for that right now. |

A proposal I would support would be 8 ranking points for AC1 and First pick, and decreasing from there. This would give 3rd robots 0 extra points compared to the pack, but the difference between the last robot and the first is only 8 rather than 6. Then the NE Eliminations points could be bumped to 10/15/25/35 to make up for the point loss and emphasize results more. Alliance Points: 8-8-0 7-7-0 6-6-0 5-5-0 4-4-0 3-3-0 2-2-0 1-1-0 Using BAE as an example: (10/15/25/35 + Alliance Points) 43-43-35... W 17-17-10... QF 21-21-15... SF 20-20-15... SF 14-14-10... QF 13-13-10... QF 27-27-25... F 11-11-10... QF |

One thing I keep coming back to with the proposed system for elimination points is the situation where the two strongest alliances at an event happen to face off before the finals. The bracket-style tournament is very effective at determining the best alliance, but it doesn't work as well when it comes to ranking the remaining seven alliances. For example, let's say the higher seeded alliances all win their quarterfinals. Alliance #3 squeaks out a semifinal win over Alliance #2 in three close matches, but then goes on to win two very one-sided finals matches against Alliance #1. Based on this, it would be reasonable to say Alliance #2 is stronger than Alliance #1. Under the proposed system, Alliance #1 would receive twice as many points as Alliance #2 (who all evidence would suggest is the stronger alliance) based purely on the structure of the bracket. I can't think of a good way to deal with this situation, short of a complex system that takes "strength of schedule" into account, or a different structure for elimination rounds (neither of which I think would be the right answer). But I do think that it's an important thing to keep in mind when creating a system like this. |
Re: 2013 NE FIRST District Rankings
Has anyone run the numbers with the FiM or MAR points system so that its easy to see the difference between the current NE proposal and the FiM or MAR models?

Re: 2013 NE FIRST District Rankings
To add to the dicussion I did a quick World OPR Rank VLOOKUP for the NE Teams (Thanks to Ed & Ether's data)
This is by no means enough for ranking into DCMP or WCMP, it just gives a screenshot of offensively which teams should maybe make it into the top NE slots... and is just meant for comparison (ie if there is a team in 10th OPR that doesnt make it into the top 50 of our ranking system, its worth looking at to make sure the NE Ranking structure is a good balance). I do believe some of this will balance out by normalizing for a single event... Note: the numbers here are the OPR Ranks for World OPR Ranking, NE OPR Ranking and Jack/Brian's NE Ranks sorted by OPR EDIT - HUGE Apologies - I forgot Rhode Island!! Added now! Code:
Team/ World OPR/ NE OPR/ NE Rank |

Alliance 2 has 6 wins in elims totaling 6*5 = 30 pts. Alliance 1 has 4 wins in elims (2 from QF, 2 from SF, 0 from F) totaling 4*5 = 20 pts. Alliance 3 has 3 wins in elims (2 from QF, 1 from SF) totaling 3*5 = 15 pts. This solves the issue Jack was referring to as well. If you include picking points with this, then you are not rewarding teams doubly for being picked and being quarter finalists. These alliances would only be granted additional points if they won a match in the quarter finals. Notably, this would also provide a good way to reward back up robots for their contributions to an alliance in elims. They would be rewarded only for the matches where they helped the alliance win. |
Re: 2013 NE FIRST District Rankings
Not to change the subject, but how about points for awards? How many should be given for Chairmans? how many for EI? Safety? Entrepreneurship? Quality? Engineering Excellence?

Kim's data suggests that there is a rank correlation of about 0.69 between World OPR and NE proposal points, which is worse than I expected. But since OPR is far from a perfect ranking measure, and we know there are problems with projecting NE district points from non-normalized Regional results, it's probably not a particularly useful measurement anyway! |

Re: 2013 NE FIRST District Rankings
I like the idea of giving alliances credit for forcing a third match.
