Agree on travel time being comparable. I used to have two sets of wheels for a 700c touring bike. One set had heavy duty rims for touring, 37mm wide tires, etc. And one set were 25mm, high pressure, thin tread with supple casings. The 25mm tires felt unbelievably faster, but when I got home after a 20 mile ride the 25mm tires resulted in about a 3 percent reduction in moving time. I consider a 3 percent difference to be not much more than round off error.
