Yeah that's what I wanted: most gain for shortest tail. A shorter tail gains less overall and a longer tails gains less per inch.

Maximum rate of change = sweet spot.

This is not a maximum effort, win at all costs thing for me. Starting with such a BIG vehicle means I can't go whole hog with a boat tail and such poor aerodynamics means the low hanging fruit should yield big percentage points.

2mpg means twice as much to the guy getting 15 mpg as to the guy getting 30. Hope my objective here makes sense
