Distribution of all available NIRCam imaging, ∣β∣ < 10°, as of 2026 September. The median number of groups per integration N = 6 (dashed line) corresponds to a minimum gain in sensitivity for trailed sources of 0.9 mag if reprocessed with group differencing, under the background-limited noise floor. Scaling our empirically measured average increase in sensitivity of 1.1 mag for trailed sources at N = 4 groups (from injection/recovery simulations) by the same ﹩\sqrt{N-1}﹩ SNR dependence yields an estimated gain of 1.4 mag at N = 6.
