Yes, that is what we found. (There is a second maximum at very low pressures, like below 40 psi for a 25 mm tire). As you point out, the differences, while statistically significant (we had so much data that it was easy to filter out the noise), don't really matter in real life. "Just ride" really is a good way to think about tire pressure. It's nice to know that obsessing about tire pressure doesn't gain you anything. I now inflate my Grand Bois Hetres to about 45 psi, and then ride them for a few months, until they start washing out under hard cornering, at which point I inflate them again. It's nice not to worry about tire pressure more than a few times a year. I do reduce the pressure if we are heading over long, rough gravel sections, but then I hardly ever re-inflate them even if we are riding for hundreds of miles on pavement thereafter.
