Digital BW, The Print

This is probably within the variability of the printers, the measurements and
the dithering code.   I re-looked at the data and graphs where I came up
with 0.46 and 0.45 looks just as good (the two dotsize curves intersect in
slightly different locations).  It would be nice if the gimp-print guys had a
standard for measuring this because other printers are way off.
