The season under/over data is very compelling: Derry City have gone under 2.5 in 17 out of 18 home games and Shelbourne in 16 out of 17 away fixtures, while the league goal averages (1.4 at home for Derry and 1.6 away for Shelbourne) further support a low-scoring affair. H2H matches also produced 5 out of 8 games with under 2.5 goals. Despite some divergence in comparison metrics, the under trend is clear in both season and historical data. This makes Under 2.5 a high-confidence bet, though note that any outlier could raise totals slightly. Given the convergence of season thresholds and H2H evidence, we rate this with 85% probability. Consequently, the fallback odds calculated are approximately 1.18.
