Every score this model holds on the tracked boards, listed board by board. Nothing is averaged across boards.
Scores on each board Each rank is the board’s own: the rank it publishes, or the model’s place in the board’s own order where it publishes none. The bar shows how much of that board the model ranks ahead of. Scores from different boards cannot be compared.

Value: where it sits on the kill line Each dot is a model: further right costs more, higher scores more. The dashed lines cross at the executioner. Above the horizontal line is SOTA, the top tier; below and to the left is cheaper and weaker, the low-cost tier.
The executioner is the best value on the board: every model that costs more and scores no higher is killed.
