Great explanation, but along with that, an example of where each different progression would work... Eg, drag racing, mudding(atv), trail riding...etc

If I'm following your charts correctly, your angle degrees are referenced from the beltline(90 degree = parallel to shaft)? Seems like some confusion out there.
