Frequently asked
How many cards does Ingmar Oostrom give per game?
Ingmar Oostrom averages 3.39 cards a game across 49 Eredivisie matches — 6% above the league average of 3.19. On an Ingmar Oostrom appointment, the model multiplies every player's booking chance by 1.06.
Is Ingmar Oostrom a strict referee?
About average. The honest measure is foul-to-card conversion — the share of fouls that become bookings — and Ingmar Oostrom runs at 15.2% 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 Ingmar Oostrom'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 Ingmar Oostrom'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 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.
