Market efficiency and TRJ. The optimal TRJ of 99.6% (combination: 1xBet 1.86 + Betfair/Matchbook 3.75 + Betclic 5.00) is exceptionally tight. This reflects strong liquidity and intense competition among operators. Most bookmakers show TRJ between 92.9% (PMU) and 99.6%, with the majority clustered around 94–97%. This signals market efficiency: odds converge quickly.
Comparison vs Pinnacle. The Pinnacle reference (1.87 / 3.78 / 4.97, TRJ 97.2%) confirms no notable value on any outcome. For Coventry City (home), the best odd (1.86 at 1xBet) is slightly below Pinnacle's fair odd (1.87)—no opportunity. On the draw, Betfair/Matchbook offer 3.75, below Pinnacle's 3.78. For Hull City (away), Betclic and Betfair/Matchbook offer 5.00, marginally above Pinnacle's 4.97—an extremely fine edge, immaterial at typical stakes.
Odds dispersion and bookmaker margins. Dispersion is narrow: 1.76–1.86 for 1X2 option 1 (5.7% spread), 3.40–3.75 for draw (9.3%), 4.30–5.00 for option 2 (14%). French bookmakers (Winamax, Betclic, PMU, Unibet) generally offer the lowest TRJ (92.9–95.2%), thus the most competitive in gross margin terms. 1xBet and Betfair/Matchbook offer extreme odds but with TRJ near 99–99.6%, signalling volume strategy over margin.
Practical recommendations. No meaningful value is detectable: CalculaBet's value calculator confirms marginal inefficiency. CalculaBet's TRJ and Surebet tools reflect equilibrium: exploiting the 99.6% TRJ requires backing all three outcomes (a capital-intensive approach). For a single-bet bettor, margin minimisation matters: prefer Betclic or PMU. No arbitrage detectable; the market is in competitive balance.
