J. Tjen vs Y. Starodubtseva — prediction
Consistent bounce, medium-fast: neutral conditions, no style favored.
Strong heat: warm air speeds the ball up and physical wear tells in long matches.
Very dry air: the ball travels faster.
Some wind: makes baseline control harder.
Moderate altitude: the ball flies a little more than at sea level.
Surface feeds the model (surface specialization is one of its factors). Weather and altitude are context we publish for you — they do NOT move the probability.

The model makes J. Tjen the favorite with a 58% win probability, against Y. Starodubtseva's 42% — a tight match, without a wide margin. Converted to odds, that probability is worth about @1.72; the offered odds are around @1.67 (a 60% implied), virtually the same as what the market prices in.
Several factors explain the number: #35 vs #74 (better ranked); performs +8% above baseline (53% career on the surface); 5/10 in recent matches; 3 matches in the last 2 weeks.
Read it with perspective. Our probability is calibrated — when the model says 58%, 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 42 out of every 100 times Starodubtseva 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.
