I tend to stay at 8.2 for pump gas drivers, 9.5 for gasoline weekend warriors and 11.5 or maybe a little more for methanol race stuff. These are just my own baselines, we all have different methods.
Trail cruising to Mud racing is quite a big span to build around. I would probably just leave it at 7.3 and spin the blower a little harder. Trail cruising a blown alky setup may be a thing of the past once you find out how much fuel it actually takes to drive around.
