-0.6σ gap
wOBA (actual)0.322
xwOBA (deserved)0.303

Riley’s wOBA sits at 0.322, but the quality of contact underneath says it should be 0.303 — a gap of 0.019, -0.6 standard deviations from the MLB norm over 304 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
