Bottle Rocket into the 8's in the 1/8 with slipping clutch

I'm not sure I buy the longer gear spread is better with spray logic. I get that the nitrous will flatten the HP/tq curves. However, to make power you need to move as much air as possible. How to move more air with less cubes is to increase rpm. So if that is true, wouldn't it be more advantageous to keep the revs as high as possible with a shorter gear spread?!
