In two-dimensional, non-relativistic, fully kinetic, collisionless electron-ion GEM-type Harris-sheet reconnection at reduced mass ratio 25 and the fixed physical geometry and normalization of the supplied guided regime, the seed-ensemble mean late-window normalized flux-slope reconnection rate at Ti/Te = 1 is at least 25 percent larger than at Ti/Te = 20 (mu_1 / mu_20 >= 1.25), and this endpoint contrast persists under a numerical-fidelity control.
