That is wildly different from the conditions most people use to apply chain lube and probably benefits lubes which don't use a solvent as a delivery system. The use of only three chains for all the lubes means that the initial wear conditions change from lube to lube. You might dismiss this as nitpicking, then again, I'm not the one claiming +-.02W accuracy in my measurements.
You want a real answer, you pony up $2k for 30 chains and run them each on that machine for several 10's of hours making measurements along the way, characterizing how the chains wear and how the resistance curve changes in time. But this is a magazine study that had to be done inside a day or two so the author could make the submission deadline. This information is actually worse than no information as it is almost certainly wrong. I would rather have acknowledged uncertainty than false certainty.
