How the Mestari diagnostics actually score you.
No Buzzfeed quiz logic. No astrology layer. A 12-16 question multi-axis instrument calibrated against named sources. Below: the engine, the axes, what we claim, what we do not, and how to read your result card.
What the diagnostic actually does
The Read diagnostic is not a personality quiz. It is a 12- to 16-question multi-axis instrument that estimates your decision quality on three independent axes: PROCESS (do you frame the decision before placing it), DISCIPLINE (do you size your stake to your conviction, not to your mood), and RECOVERY (do you exit a losing session before tilt compounds losses).
Each question is calibrated against a known correct answer drawn from the PUTKI HQ source library — Wizard of Odds for game math, Casino.guru independent reviews for operator behaviour, and academic gambling research (Williams, Volberg, Stevens 2012 and follow-up Finnish studies via THL) for self-regulation patterns. There is no Buzzfeed quiz logic. There is no astrology layer. The result card is a four-quadrant placement plus a per-axis percentile.
The three diagnostics share an engine
Sports (/mestari/sports), Poker (/mestari/poker) and Blackjack (/mestari/blackjack) all run the same scoring engine — what differs is the question bank. Sports questions reference closing line value + bankroll fraction sizing. Poker questions reference pot odds + position discipline. Blackjack questions reference basic-strategy adherence + tilt-recovery behaviour. The axes are identical because the underlying skill is identical: the ability to act on probability under emotional load.
A reader who completes all three diagnostics gets three independent four-quadrant placements. Cross-axis comparison is more diagnostic than any single result — process can be high on one game and collapse on another, which is where the highest-leverage improvement work usually sits.
What we do NOT claim
The diagnostic does not predict whether you will win money. It is not a "+EV detector". It scores the quality of your decision framework against a calibrated reference. A reader with a 95th-percentile PROCESS score can still lose money on -EV games — the diagnostic just tells you that the leak is not in your decision quality, it is in the games you are choosing to play.
We also do not claim the instrument is medically diagnostic. If your result card surfaces low scores on the DISCIPLINE + RECOVERY axes alongside high self-reported play frequency, the result card always carries a link to Peluuri (the Finnish state gambling-harm helpline). Mestari is editorial. Peluuri is clinical. We do not blur that line.
Sample sizes and calibration
As of February 2026 the three The Read banks have aggregated ~12 400 completed diagnostics across all three games. Calibration is re-run quarterly: the question bank gets a Cronbach's alpha score per axis (current targets: PROCESS ≥ 0.82, DISCIPLINE ≥ 0.78, RECOVERY ≥ 0.75) and any question that drags the alpha below threshold is rotated out. The current bank passes all three thresholds for all three games.
Percentile placement is computed against the rolling 90-day population for the same diagnostic — this prevents seasonality drift (poker scores tend to inflate during major tournament seasons; sports scores compress during Veikkausliiga off-season). All raw results are stored hashed; no individually identifiable result is ever exposed to operators.
How to read your result card
The four-quadrant placement is the headline. Top-right means high process AND high discipline. Bottom-left is the failure mode. Top-left means you think well but stake badly — the most common pattern in our data. Bottom-right is the rarer "instinctive operator" — discipline without framework, often a recipe for streak-dependent variance.
Below the quadrant, the per-axis percentile bar shows where you sit against the 90-day cohort. The result card finishes with two or three concrete moves — these are pulled from a curated playbook (PUTKI HQ Operator Runbook §M-4), not auto-generated from your score. Same score, same moves. Reproducibility is part of the editorial contract.
