HOW EACH FACTOR MATTERS
Level (Elo/ranking)▸ Feldbausch●●●
Elo rates Feldbausch ahead, 1861 vs 1782, giving him a 61% baseline win probability against Kopp's 39%.
Serve/return▸ Feldbausch●●
Kopp serves better (64% vs 62%), but Feldbausch's return (47% vs 43%) gives him the larger net edge in points played.
Form▸ Kopp●●
Kopp's last 10 shows 8 wins to Feldbausch's 7, a modest recent-form edge for the underdog.
Altitude▸ Kopp
At 760m the thinner air adds pace to serves, a mechanism that mildly helps the better server, Kopp (64% vs 62%).
Weather▸ Feldbausch
80% humidity thickens the air and slows the ball, blunting Kopp's serve edge and helping Feldbausch's stronger return (47%).
Rest= Even
Both reached the Kitzbuhel semifinals 1 day ago with identical rest (3 matches in 14 days) — a symmetric, non-differentiating factor.
ELO EDGE

Feldbausch enters this ATP Kitzbuhel qualifying match as the rating favorite, with an Elo of 1861 against Kopp's 1782. That translates into a 61% baseline probability for Feldbausch versus 39% for Kopp, a gap that is real but modest for a match at this level.

Recent form runs the other way, though: Kopp arrives with an 8-2 record in his last ten matches (WWWWWWLWLW) compared to Feldbausch's 7-3 (WWLWWWWLLW), which included a two-match losing stretch late in his run. Neither signal is decisive alone, but together they suggest a match closer than the rating gap implies.

SERVE BATTLE

The serve-and-return numbers give a mixed picture. Kopp is the better server on paper, winning 64% of his service points against Feldbausch's 62% — a small two-point margin. But Feldbausch's return game is sharper, converting 47% of return points versus Kopp's 43%, a four-point edge that outweighs the serve gap.

Net, this points to Feldbausch having a slight advantage once points are actually contested, even though Kopp holds the raw serving statistic.

CONDITIONS AND FATIGUE

Kitzbuhel sits at 760 meters, a moderate altitude that thins the air enough to add a touch of pace to serves — a mechanism that, if anything, nudges toward Kopp given his higher service percentage. Working against that is the weather: 80% humidity and a mild 17°C thicken the air and slow the ball down, a condition that tends to shorten the advantage of a big server and favor the better returner, which here is Feldbausch. The two effects largely offset each other.

Fatigue is not a differentiator here: both players reached the Kitzbuhel semifinals a day ago and carry identical rest profiles (1 day off, 3 matches in the last 14 days), so neither side gains a scheduling edge.

VALUE READ

The market prices Feldbausch at a 78% implied probability (odds of 1.29), well above the model's 61% Elo-based estimate — a 21% negative expected value. Even allowing for the Elo figure being a soft, Challenger/ITF-style read on a qualifying-level match, the gap is large enough to flag caution.

The market is treating this as a bigger mismatch than the rating difference, the mixed recent-form signals, and the comparable serve-return numbers actually support. Being the favorite here does not mean the odds offer value; on this evidence, they do not.
