Change in PFL2 membrane potential (Δ V m ) before and after each 180° jump, comparing corrected jumps with high ρ ( n = 31 of 276 jumps) or uncorrected jumps with low ρ ( n = 27 of 276 jumps). Variance in Δ V m is higher for corrected versus uncorrected jumps ( P = 0.01363, Brown–Forsythe test). See also Extended Data Fig. 7 .
