Also, it shouldn't matter which mode you use up stamina in. It should still charge the special stage gauge either way.
That is correct though even with the half stamina story maps I am only getting the 10 point senkai once working out at 50 points per 25 stamina, which is less than my average on the hell maps (being 60). Seems the more stamina you use the better chance of higher points.
