›Ranking: #37 vs #137 (better ranked)
›Head-to-head: 1-0 in favor
›Model 61% vs market 50% → the model sees it as MORE likely than the odds
The model makes M. Arnaldi the favorite with a 61% win probability, against R. Sakamoto's 39% — a solid favorite, though Sakamoto keeps real chances. Converted to odds, that probability is worth about @1.63; the offered odds are around @1.99 (a 50% implied), slightly above the market, so the model is a touch more optimistic.
Several factors explain the number: #37 vs #137 (better ranked); 1-0 in favor; model 61% vs market 50% → the model sees it as more likely than the odds.
Read it with perspective. Our probability is calibrated — when the model says 61%, that outcome happens roughly that percentage of the time, with ~65% out-of-sample accuracy — but being the favorite is not being the winner: roughly 39 out of every 100 times Sakamoto 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.
