Vaguely on topic… theoretically, would it be better to train at maint calories or at a slight surplus? Obviously you’d need to take into account that with a surplus you’d need to go into deficit for a few weeks to deal with any weight gained. This without getting into anything as complicated as nutrient timing for training sessions / events.
I guess you wouldn’t really be putting on significant muscle at maint, beyond a little bit of body recomposition.
