Frequently asked
How many cards does Robert Hartmann give per game?
Robert Hartmann averages 3.69 cards a game across 49 Bundesliga matches — 10% below the league average of 4.09. On a Robert Hartmann appointment, the model multiplies every player's booking chance by 0.90.
Is Robert Hartmann 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 Robert Hartmann runs at 17.0% against a league average of 18.5%. Foul counts barely vary between officials; the rate at which a foul becomes a booking is where referees genuinely differ.
Does Robert Hartmann'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 Robert Hartmann's card rate?
It rests on 49 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.
