Frequently asked
How many cards does Joao Antonio Ferreira Goncalves give per game?
Joao Antonio Ferreira Goncalves averages 5.15 cards a game across 66 Primeira Liga matches — roughly at the league average of 5.17. On a Joao Antonio Ferreira Goncalves appointment, the model multiplies every player's booking chance by 1.00.
Is Joao Antonio Ferreira Goncalves a strict referee?
Slightly, yes. The honest measure is foul-to-card conversion — the share of fouls that become bookings — and Joao Antonio Ferreira Goncalves runs at 19.7% against a league average of 19.0%. Foul counts barely vary between officials; the rate at which a foul becomes a booking is where referees genuinely differ.
Does Joao Antonio Ferreira Goncalves'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 Joao Antonio Ferreira Goncalves's card rate?
It rests on 66 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.
