After many folks whose advice I trust told me I was wrong to ignore
double coating cyanotypes I did some more testing. Sure enough, with a lot
longer exposure the double coating did give a slightly better DMAX. It also
gave me a slightly shorter scale. I was using Canson Cold Press and classic
1:1 cyanotype.
Then I tried to repeat my tests with Fabriano Aristico--well, that paper
definitely needs double coating.
So, for my purposes anyway, on this paper anyway, the single coating is
faster and has a longer scale.

Many thanks to all who answered me. I have learned a lot.
