i will concede everything if someone has hard evidence to refute my experiences.

i will also concede that my statement near the end of my post in which i stated the savings would equal the ratio change is not very likely to be true except in some exceptional situation. but my statement in the first part of my original post said nearly equal, and i will stand by that.

now we can argue about what nearly means, i suppose, but i would like to see evidence.

even engineers eventually have to put the car on the road and see if their calculations are correct.

even mercedes conducts extensive road testing and we all agree they have the best engineers in the world, right?
