Upset Percentage
Does anyone have a percentage of all elimination matches, within all divisions, and extending onto Einstein, that were upsets (lower seed beating higher seed)? Competitions this year were insane, and from my knowledge, I'd say by far the most unpredictable in FIRST's history (at least since 2011). Can I get some older vet's opinions on this? Also, I'd like to hear opinions on why.

Re: Upset Percentage
To rephrase, and hopefully garner some more conversation/thoughts, here are the outcomes and calculations.
Each field has 4 Quarterfinal pairings (Q), 2 Semifinal pairings (S) and one Final pairing (F) for a total of 7 pairings. With 8 division fields and Einstein, we have 9 fields total, with 7 pairings each, for a total of [edit fixed: 63] pairings. Pairings with upsets: Archimedes Alliance 3/2 - S - 1 Carson Alliance 5/4 - Q - 2 Alliance 7/2 - Q - 3 Alliance 4/1 - S - 4 Alliance 4/3 - F - 5 Carver Alliance 5/4 - Q - 6 Alliance 6/3 - Q - 7 Alliance 2/1 - F - 8 Curie Alliance 8/1 - Q - 9 Alliance 7/2 - Q - 10 Alliance 6/3 - Q - 11 Alliance 5/4 - Q - 12 Alliance 8/5 - S - 13 Alliance 7/6 - S - 14 Alliance 8/7 - F - 15 Galileo Alliance 6/3 - Q - 16 Alliance 6/2 - Q - 17 Hopper Alliance 7/2 - Q - 18 Newton Alliance 7/2 - Q - 19 Alliance 7/3 - S - 20 Alliance 7/1 - F - 21 Tesla Alliance 3/2 - S - 22 Einstein Alliance 8/1 - Q - 23 Alliance 7/2 - Q - 24 Alliance 6/3 - Q - 25 Alliance 6/4 - S - 26 Alliance 7/6 - F - 27 Above you see that 27 out of those edit [63] pairings were upsets, giving us an upset rating of 42.8%. So has anyone in FIRST ever seen anything quite this unpredictable before, or was this the most unpredictable Championship you've seen? Why? |
Re: Upset Percentage
On Galileo 6 also beat 2 in the semis.
Not counting Einstein - that would 22 upsets out of 56 (7*8) or 39.3%. |

Looks like a typo. Last I knew, 7*9 was 63, not 36.

I didn't watch Curie, so I'm not sure how things went down. It did seem easier, however, for the lower seeds to scoop up some high goal scorers/scalers in the later picks. I'm going under the assumption that the top half or so were strong enough that no one stood out more than another, so the #5-6 pick would be able to match the output of a #1 pick, #8 captain was strong enough to pick robots to match the output of #1 alliance, etc. |

[Edit] That being said, will FIRST introduce so many possibilities for ranking points next year? Maybe not. I certainly hope not. I remember in 2012 coopertition points were a boost to the good and the bold. 2012 IMO was a very good example of how dual ranking points could highlight really above average teams. This year however, instead of being a boost, it was a possible equalizer. I think it probably looked good in theory / on paper, but not in the actual season. Heck, I wouldn't care if we went back to seeds being fully reliant on W/L/T. Good scouting will bring out the best. |
Re: Upset Percentage
The fact that Curie division had a 100% upset in the bracket proves that the scouting data those teams had were beyond poor. Besides the fact we knew the number one seed was unlikely to win because they were not a high goal shooter, it should have been much easier to make stronger alliances by checking for high goal consistency.
Our data which I think we can release soon will show that 3339 with a range of (2-9) and 836 with a range of (4-7) were the two best high goal shooters by our own judgement in the division and that nobody else caught it. They were both second picks which I find ridiculous considering the number of shots they made and with such consistency. Honorably mentions to 166 (1-7) and 3641(0-8) who are also really good high goal robots. What it came down to was how the robots were designed and if a defender could stop them, where they shot from, did they score 0s, etc. It would have been terrifying if 876 and 3339 were on the same alliance and that almost happened! |

It was the result of the ranking system that rewarded getting just enough poiints to win low-scoring matches, two separate tasks that became integrated into elimination scoring. So 3 separate tasks became only in the playoffs. As a result schedule became even more important. An unbalanced schedule allowed certain teams to accomplish those tasks more easily thanks to the help of stronger teams, and stronger teams were hurt when an alliance mate failed to accomplish a task. If 686 had not gotten back to the batter in time in the last match for 148, Hopper would have looked a lot more like Curie. |

I will attached our top 20 posted scores which we did later edit for consistency. (Not to discredit any team because I love this robot design) 1983 crossed 28 defenses, scored 21 high goals, and scored 7 low goals in the qualifications which put them in our data after we ranked for consistency around 15th in overall effectiveness in Curie for a high goal shooter. I would be interested in seeing their data because I loved their graphic color charts and the way the data is organized. Maybe I am misunderstanding the term "producing" but they scored a lot less defenses (41) and half as many high goals (48) as the highest robots in those scoring categories. This is why I was confused at the alliance selection when there were many other robots that should have bubbled to the top a lot faster. 3339 and 876 being prime examples, what if 1089 had picked one of them! Either way, it was an exciting and interesting turn of events in Curie :D |

Here is a spreadsheet I made for English class with all the upsets from the past 4 years: https://docs.google.com/spreadsheets...it?usp=sharing

Re: Upset Percentage
Something I think a lot of teams did across the board for champs that might not be ideal was scouting defense crossings and using that to help calculate overall scores for robots. We opted to not even scout crossings since the breach is guaranteed at the championships level. That being said I wish we did scout crossings just so we can compare what our overall scores list would look like when comparing crossings vs without crossing. I would imagine teams that focus more on poaching the enemies secret passage would move up in our scouting ranking vs teams that cycle.

Handy table for the odds of a perfect reverse bracket
50% odds of underdog winning-->Once every 128 tournaments 45% --> once every 268 tournaments (roughly 2 years) 40% --> once every 610 tournaments (roughly 4 years) 35% --> once every 1554 tournaments (roughly 10 years) 30% --> once every 4572 tournaments (roughly 30 years) 25% --> once every 16,384 tournaments (roughly 100 years) 20% --> once every 78,125 tournaments (roughly 600 years) |

Thus, #1 is always red. #8 is blue, but can take over red if they beat #1. #2 is red, unless they're in finals; #7 is blue unless they beat #2. #3 is red against #6, and blue otherwise (#6 is always blue). #4 is red against #5, blue for semis, and red for finals (while #5 is blue unless they're in finals). Or, to put it another way: Alliance: QFs, SFs, Fs (assuming they make it that far) #1: R, R, R #2: R, R, B #3: R, B, B #4: R, B, R #5: B, B, R #6: B, B, B #7: B, R, B #8: B, R, R Best reason to be on the #1 alliance, you don't change your bumper color. (OK, so #6 has the same perk...) |

This SQL may not be the most efficient, but it works: Code:
select distinct events.name as Event, match_levels.name as Round, matches.set_number as Number, matches.match_number as Match,712 of 2273 playoff matches were upsets. That's 31.3% 643 times Blue was the underdog and upset Red. 69 times Red was the underdog and upset Blue. Whew.... I hope that's it. Are there any other quirks of the system that I have missed? (Now, I have to get back to work!) |
