These are Richard Martens'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 and 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 Richard Martens turns into bookings. Conversion, not the raw foul count, is where a referee's real card tendency lives. Career figures across every Eredivisie season on record.

Frequently asked

How many cards does Richard Martens give per game?

Richard Martens averages 3.00 cards a game across 33 Eredivisie matches — 6% below the league average of 3.19. On a Richard Martens appointment, the model multiplies every player's booking chance by 0.94.

Is Richard Martens a strict referee?

No — slightly more lenient than most. The honest measure is foul-to-card conversion — the share of fouls that become bookings — and Richard Martens runs at 14.2% against a league average of 15.4%. Foul counts barely vary between officials; the rate at which a foul becomes a booking is where referees genuinely differ.

Does Richard Martens'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 Richard Martens's card rate?

It rests on 33 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 and an opponent factor, and discounts its confidence for thin referee records, before flagging any card as value. It compares against the bookmaker's price as offered — card markets are priced one side only, so that price still carries the bookmaker's margin. 18+ — please gamble responsibly.
