I'm late to this party, but I'd like to respond.
IMHO, "cutting material on a cutting board" is not scientific enough. What's needed is the most uniform wear along the entire length of the blade.
I heard a couple times the "difference between having the test cylinder rotate".
The good thing about your test cylinder rotating is that you don't have any burr or wire edge "piling up" in the test media of a single slice. That negates artificial galling, which would be a huge variable.
I normally rotate the media (whatever test media- I like "Sharpies" best), because of this propensity. Especially final deburring and "destressing" (like "proving" an edge by using it).
Most people cut cardboard, which is pretty subjective, but making slices on hard plastic might be better. I like cutting manilla rope the best.
