Compatition Ranking
With the announcement of Wins/losses no longer be tracked through qualification matches we have a situation to figure out.
Traditionally teems have been awarded qualification points via wins, ties, and losses (2-1-0 respectively), this year however the first order of sorting is not number of qualification points, but rather something called Qualification Average. The orders of seeding (2-7) are what you would expect; co-op score, auto score, etc. I have no solid evidence on how Qualification Average works, the rule that this refers to is 5.3.4 in the game manual. Any Ideas? |

Re: Compatition Ranking
Read the paragraph before Section 5.3.4 starts.

You take the average score of all your matches and that's your qualification average (QA). That's what's used for ranking all the teams. IF by some large mathematical improbability teams are tied with the same QA then they are sorted by the tiebreakers referred to in 5.3.4 |

Re: Compatition Ranking
Why use the average? Why not just the total accumulated points? Every team is scheduled for the same number of matches, so why do we do the (extra) math?

That being said (since the surrogate matches do not count towards the teams qualification average) why not use the total number of points scored? I believe the answer to this is just to have smaller numbers. But this in turn introduces another problem: the average is rounded to n decimal places. Therefore co-op points, auto points, etc, come into play. Last edited by Skyehawk : 03-01-2015 at 13:18. |

Re: Compatition Ranking
Per page 52. The total number of MATCH Points earned by a Team throughout their Qualification MATCHES, divided by their number of assigned
MATCHES (excluding any SURROGATE MATCHES), then truncated to two decimal places, is their Qualification Average (QA). We are not counting the surrogate match, so we would not add the points to their total. |

Re: Compatition Ranking
Because in the middle of competition not all teams have played the same number of matches.

Re: Compatition Ranking
But the rankings don't matter until alliance selection.

Re: Compatition Ranking
They don't directly impact any aspect of the competition until alliance selection, but it is nice to know where your team lies prior to that.
It is also useful information when talking to other teams about alliance selection. |

Re: Compatition Ranking
But mid-tournament rankings can affect strategy in upcoming matches. In a very simple (and naive case), if you're quickly trying to determine if you still have a chance at making the top 8, you may want to see the relative strengths of the teams ahead of you, and tracking the averages is more helpful than total scores because it helps normalize across # matches played. (Clearly you should be keying in on the robot's abilities rather than just their total points scored w.r.t your match strategy, but ranking certainly is an important indicator as well).

Re: Compatition Ranking
My big question is if we are taking an AVERAGE score, then why leave out a surrogate match. Why not have that team's average be based on 11 matches instead of 10 (or whatever the case may be)? I can see in a Win/Loss scenario, or even if we were going with total points, but going off an average?
My fear is that teams will adopt the strategy of sabotaging their surrogate matches. If it doesn't count against them, why not lower the other teams' average? Granted, definitely NOT in the spirit of FIRST, but you know teams will do it. If we did away with surrogates this year, and let a few teams have an extra match figured into their average, I don't see where it would hurt. |

Re: Compatition Ranking
My other question; Is ranking averaged match-by-match as the day goes on, or is it always calculated by the number of matches scheduled?
Example: After 3 matches, a team has 330 points. They are scheduled for 10 Qualifier matches. Is their current average 110 (330/3) or 33 (330/10)? |

Perhaps it is a way to normalize scoring across events for district points? |
