Digital BW, The Print

Out of curiosity I measured all matte papers that I have in house. I 
used X-Rite DTP20UV:

                L        a        b      R        G        B
------------------------------------------------------------------
PremierArtBW    94.14    1.05    -2.02   238.86   237.55   242.05
Moab Kayenta    96.16    0.49    -2.29   243.33   243.71   248.36
EEM             96.68   -0.28     0.61   245.25   245.55   244.21
Moab Entrada W  97.06    0.59    -0.83   247.13   246.16   248.14
Epson ScrapBook 96.87   -0.06     2.01   247.18   245.90   242.01
PremierArtFA    96.73    0.06     2.03   247.03   245.42   241.63
------------------------------------------------------------------

Results are a bit of surprise for me: I thought that PremierArtBW
is actually brighter than PremierArtFA (205), or that EEM will have 
the most neutral tone from all measured papers.
