-0.7σ gap
wOBA (actual)0.344
xwOBA (deserved)0.325

Stephenson’s wOBA sits at 0.344, but the quality of contact underneath says it should be 0.325 — a gap of 0.019, -0.7 standard deviations from the MLB norm over 487 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
