Truly fascinating! I'm still not entirely convinced, but can accept that the geometry might not be as big of a factor as I currently think.
Assuming that the media would only need to be severed to 25% of its diameter to fully separate, that's still over 60 microns. If an edge was at 30 degrees inclusive, and the edge width was less than a micron, the blade width at 60 microns penetration would be over 30 microns (i.e., the width at 60 microns "up" from the edge, which presumably would be in contact with the media to some extent). I have to believe this has some effect on the reading, but I can also accept that the total effect might be smaller than, say, the difference between using the test clips instead of the spool, and therefore doesn't explain the knife vs chisel paradox (another theory shot down by facts).
