These are Stephen Martin's own match figures — the raw card and foul counts from the matches covered. They're not adjusted for how aggressive the two teams are or whether it's a derby. The model layers those in — the referee tendency, each player's booking rate and an opponent card-induction factor — to price a specific leg. That combined verdict is the locked price · edge.

Career profile

The two numbers that matter are vs league — the multiplier the model applies to a player's booking chance — and conversion, the share of fouls Stephen Martin turns into bookings. Conversion, not the raw foul count, is where a referee's real card tendency lives. Career figures across every Championship season on record.

Frequently asked

How many cards does Stephen Martin give per game?

Stephen Martin averages 4.50 cards a game across 96 Championship matches — 12% above the league average of 4.01. On a Stephen Martin appointment, the model multiplies every player's booking chance by 1.12.

Is Stephen Martin a strict referee?

Slightly, yes. The honest measure is foul-to-card conversion — the share of fouls that become bookings — and Stephen Martin runs at 19.5% against a league average of 18.4%. Foul counts barely vary between officials; the rate at which a foul becomes a booking is where referees genuinely differ.

Does Stephen Martin's record change bet builder card prices?

It should. The referee is the single biggest factor in the to-be-carded market, and the appointment is public before kick-off — so a strict official on a combative player is the archetypal card edge. The player cards guide walks through exactly how the model turns a tendency like this into a price.

How reliable is Stephen Martin's card rate?

It rests on 96 career matches, a solid record. The model shrinks a referee's tendency toward the league average when the sample is thin and discounts its own confidence for officials with young records, so a number like this never gets trusted beyond what the evidence earns.

Rates shown are figures from public match data for context; the model adds shrinkage, an opponent factor and de-vigging, and discounts its confidence for thin referee records, before flagging any card as value. 18+ — please gamble responsibly.
