Ah. Ok. Mine are bigger (replacement for 195/50R16), so that may be a factor.
Again, great test. I've been meaning to suggest this to some friends doing official tests on a "fuel-saving" tire from another manufacturer. They measured consumption as the average consumption over dozens of (tightly-controlled) laps over a closed circuit versus a control tire. Was going to participate, but had prior engagements. Was thinking they could also test rolling resistance directly, too.
