Re: Analysis of team ranking

Quote:
- these results list a couple teams as providing negative points on average -- this is fairly clearly not true. These teams probably contribute about 0 points on average. This actually gives a pretty good rough estimate of the precision of these numbers (error of ~3 should be expected on all numbers)
That's not entirely true - the way the math works out, you end up solving for "the number of points added by that team being in an alliance". If a team tends to take fouls, gets in the way, blocks visibility, or breaks their alliance partners, they may end up with a negative value.

Similarly, it is possible for a team to have a positive value without ever scoring a single piece: if the team facilitates scoring in some way (good strategy, supplying parts, bringing a ramp, etc), they may still have a positive effect on the alliance's score.

Your other points about limitations are correct.
