$ how the score was worked out · LFM2 Technical Report — Liqui… 93%, EuroEval leaderboards (result… 6%

Each result implies a score on its own, after adjusting for how hard its test is and who ran it. The score is their weighted average, with a small pull toward the middle for thinly tested models. Each test's weight is its counts column above; here it's added up by who ran the tests. How it works
