From the evidence, I can see several numeric measures: 'Best score (across scorers)', 'Parameters', 'Training compute (FLOP)', 'Training compute cost (2023 USD)', 'Citations', etc. The 'Best score (across scorers)' appears to be the primary performance metric since this is a benchmarking dataset. However, I should examine all available numeric columns to make an informed decision. Let me query to see the full list of numeric measures and their characteristics.",
