On paper, flat staking at average odds, Elo/player-state model (an earlier, now-retired version — today's Daily Pick uses the factor forecaster you see across the rest of this page, with its own 65.5%/Brier 0.213 measured separately). Includes 2024 in the red (−4.2%) — we don't hide it. Annual average +3.6%. High variance; past doesn't guarantee the future.

How it works
STEP 01 · EVERY MORNING
The engine trains on ~186,000 matches
A calibrated factor model — ranking, form, surface, rest, head-to-head, Elo and more — trained on a database of ~186,000 matches across every tour. No hunches: only what can be measured goes in.
STEP 02 · TODAY'S MATCHES
Probability + the why, match by match
Every match gets scored across a per-match dossier of dozens of signals — H2H, form, serve/return, surface fit, rest, Elo, venue weather — producing a calibrated probability, the comparison with the odds, and an explanation of how each factor tilts the match.
See today's matches →
STEP 03 · THE NEXT DAY
We settle in public, right or wrong
Every published prediction is settled against the official result and feeds our live accuracy — visible to anyone, no spin. So you know exactly how often we're right before you trust us.

Parlay advisor
Building a parlay? Pick your legs from today's real matches and we rate the whole thing before you bet it: combined probability, the fair odds it should pay, its expected value (EV) versus the price on offer, and a plain verdict — VALUE, FAIR or SUCKER. Most parlays are a bad deal; this tells you which ones, and why. Premium.

Frequently asked questions
Does it guarantee I'll make money betting?
No, and be wary of anyone who promises that. Our own research (published on Transparency) shows the model matches the market on average: the odds already capture nearly all the information. Baseline gives you the best probabilistic read on the match and the why — not guaranteed profits.
How accurate is the model?
The daily pick hits 71.4% (2023–2026 frozen walk-forward validation of the published selection rule, n=1,081). Match by match, the model measures 65.5% on ATP and 65.1% on WTA out of sample — and now also live: every published prediction is settled against the official result and the cumulative accuracy is public. Being the favorite isn't winning: 70% means missing 30 out of every 100.
Where does the data come from?
Over a decade of match history with closing odds (ATP and WTA), official results and stats from a sports data provider, real weather for each venue, and our own archive of odds captured daily. Every data point in the analysis has a source; what doesn't, we don't publish.
What does the Free plan include and what does Premium add?
A free account gives you 3 days of full Premium (no card); after that you keep today's pick, the read of every match — probability, model reasoning and context (ATP, WTA, Challenger, ITF) — tour stats and live accuracy. Premium, €9.99/month (or €89 for the whole year), adds the value verdict (fair odds, expected value), the full factor-by-factor analysis, the parlay advisor and the ELITE picks. Cancel anytime · full comparison.
Do you cover Challenger and ITF?
Yes, with honesty about the method: ATP and WTA use the validated factor model; on Challenger/ITF the probability comes from real Tour Elo and is labeled a soft-market estimate, because there the model doesn't yet have equivalent validation.
Why should I trust you?
Because you can not trust us and check for yourself: we publish live settled accuracy, calibration by probability band, the full backtests, and even the experiments that failed. Transparency is the product — if the numbers get worse one day, you'll see it before we tell you.
Start free — see what the model sees
Free account in 30 seconds, no card — and it opens 3 days of full Premium. After that, today's pick, every match's read — probability, reasoning and context — and tour stats stay free. Premium (9.99€/mo) keeps the value verdict (fair odds, EV) and the full factor-by-factor analysis.
