While One‐way ANOVA tests indicated minor statistical variations among the samples within the same channel (p = 0.0132 for the 1.0 mm channel; p = 0.0035 for the 1.6 mm channel), these maximum deviations (∼0.27 mm/s) were negligible compared to the highly significant performance shifts induced by variations in the environmental geometry (an absolute speed difference ranging from 1.8 to 2.3 mm/s, p = 2.27 × 10 −5 when comparing the pooled sample data between the two channels).
