BREAKDOWN · MODEL ANALYSIS

The model makes V. Golubic the favorite with a 59% win probability, against E. Kalieva's 41% — a tight match, without a wide margin. Converted to odds, that probability is worth about @1.71; the offered odds are around @1.50 (a 67% implied), slightly below the market, so the model is a touch more cautious.

Several factors explain the number: #67 vs #117 (better ranked); model 59% vs market 67% → the model sees it as less likely than the odds.

Read it with perspective. Our probability is calibrated — when the model says 59%, that outcome happens roughly that percentage of the time, with ~64% out-of-sample accuracy — but being the favorite is not being the winner: roughly 41 out of every 100 times Kalieva wins. The model also tends to agree with the market, so the odds already capture almost all the edge: don't take it as a sure value.
