Tournament tier: reliability by event level

Tournament level	Matches	Win rate

Grand Slam and Masters samples matter most for pricing; ATP 250/500 volume often inflates or deflates the headline win rate. Cross-check against Tommy Paul or Francisco Cerundolo for other ranks-21–50 archetypes.

Round-by-round: early rounds vs deep runs

Round	Matches	Win rate
1R	76	56.6%
2R	20	50.0%
3R	7	57.1%

SF	5	20.0%
F	1	0.0%

Round curves separate true closers from early-round specialists. A drop at QF/SF is a fade signal even when the overall win rate looks healthy — the same structural idea as Rublev's late-round ceiling.

H2H against elite rivals

Rival	W–L	Win rate
Medvedev	0–4	0.0%
Sinner	0–3	0.0%
De Minaur	1–2	33.3%
Tsitsipas	3–0	100.0%
Fritz	2–0	100.0%

Elite H2H is sparse for many mid-ranked players; only rows with multiple meetings are shown. Use these as matchup modifiers, not as a substitute for surface form.

How our model treats Alex Michelsen

The ensemble weights surface win-rate history, recent form (last 5 / last 10), and tournament-tier context most heavily for a rank-21–50 profile like this. Favourite/underdog conversion is a secondary prior when odds history is dense enough (here: 80 matches with usable prices). Uncertainty rises when the next match is on a thin-sample surface or against an elite rival with a one-sided H2H.
