It's incorrect to compare a 47mm tire to a 32mm tire at the same pressure because they would never be done due to a difference in casing pressures. But really using pressure is incorrect anyway, to find the true rolling resistance the test needs to be done at equal sag for all tires.
Agreed. Good points. Still, I’m not losing sleep over a couple of watts. 20-30 watts per tire might keep me up at night. ;-(

Yeah, but velodromes are so crazy fun. I'm doing good to cruise at 20mph on the road, maybe 15+ mph on dirt, but race on the velodrome around 35mph.
