Yea, I know, sometimes I wonder that myself. What I thought I could accomplish was to establish filter grades for my particular enlargers' filter glass and not accept what the papers' manufacturer says is a grade 2, but actually prove my grade 2.

I would be happy to read the densities for you if that would help you.
This is an offer I can not refuse...
I'll PM you for further instructions, Thanks very much
