Frequently asked
How many cards does Szymon Marciniak give per game?
Szymon Marciniak averages 4.29 cards a game across 24 UEFA Champions League matches — 8% above the league average of 3.96. On a Szymon Marciniak appointment, the model multiplies every player's booking chance by 1.08.
Is Szymon Marciniak 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 Szymon Marciniak runs at 17.4% against a league average of 18.1%. Foul counts barely vary between officials; the rate at which a foul becomes a booking is where referees genuinely differ.
Does Szymon Marciniak'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 Szymon Marciniak's card rate?
It rests on 24 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.
