Can > you re-send with "delay_200_500_e200" instead? Sure. Do I understand correctly that more conservative delay_200_500_e200 will for sure not make it worse, since its more conservative? In that case can re-spin right away. Otherwise I would prefer to re-test it first, may take a few days as I do not own the hardware so need to propagate the change and get some feedback.
