HOW EACH FACTOR MATTERS
Level (Elo/ranking)▸ Korpatsch●●●
Elo 1521 vs 1476 and a #78 vs #913 ranking gap produce an 84% model probability, a clear class advantage for Korpatsch.
Form▸ Stusek●●
Korpatsch is 3/10 with a live 1-match losing streak; Stusek, though 1/5, just snapped four straight losses, giving her momentum.
Rest▸ Korpatsch
Korpatsch had 14 days off (1 match in 14 days) vs Stusek's 2-day turnaround (2 matches), a freshness edge tempered by a 23-day layoff risk.
Weather= Even
18°C, 65% humidity and 21 km/h wind lengthen rallies and test precision, but no serve/return split exists for either player to gauge the effect.
Serve/return▸ Korpatsch
Korpatsch's 52% serve points sits 5 points above her 47% baseline, though a 37% return rate flags return-game vulnerability; no comparable Stusek data exists.
CLASS GAP

The Elo spread (1521 vs 1476) and the ranking gulf (#78 vs #913, per the model's own reference) both point the same way: Korpatsch is the far more established player, and the 84% model probability reflects that gap in class rather than any single hot streak.

This is the single largest driver of the pre-match numbers, and it is the reason Korpatsch is priced as a heavy favorite despite her recent results.

FORM VS CLASS

Korpatsch's recent form is a genuine concern: 3 wins in her last 10 matches and a current 1-match losing streak. That is the kind of drop-off the model flags as a risk even for a much better-ranked player.

Stusek, by contrast, arrives having just broken a four-match losing skid with a win, though her overall 1-5 last-10 record is still well below average. The net effect is that form narrows — without closing — the gap implied by class and ranking.

SCHEDULE AND RUST

Korpatsch has had 14 days since her last match, playing only once in the last two weeks, while Stusek is on a quick 2-day turnaround having played twice in that span. In isolation, that rest edge should help Korpatsch's legs over a potential three-set match.

The caveat is the layoff itself: 23 days without competitive minutes is flagged as a rustiness risk, which can offset some of the physical freshness advantage, particularly in the opening set.

CONDITIONS ON COURT

Warm, humid air (18°C, 65% humidity) with 21 km/h wind is the kind of setting that lengthens rallies and punishes shot-making precision. Without a documented serve or return percentage for Stusek, it is not possible to say which player's game is more exposed to these conditions.

Korpatsch's own numbers — 52% serve points won against a 47% baseline, but a modest 37% return rate — suggest a player who serves slightly above her norm but is not dominant on return, which matters if the wind disrupts her first-serve placement.

VALUE CHECK

The model gives Korpatsch an 84% chance to win, but the market is pricing her even shorter at an implied 88% (odds of 1.13). That gap produces a -5.1% expected value on the favorite — the market is not underestimating her, if anything it is slightly more confident than the model.

Being the favorite here is not the same as being a value bet. On these numbers, backing Korpatsch at 1.13 is a bet on a real class edge, but not one the data says is mispriced in the bettor's favor.
