1.5 is what I measure (after dry down) with Vuescan and a scanner (turn on
the "Prefs|Enable Density Display" option, hold the control key and hover
over a dark area of the print).

There's your problem. Vuescan in my experience doesn't give as reliable
readings as a densitometer. I think if you measured your densities with a
densitometer and compared them to what you are getting with Vuescan you
would see some troubling inconsistencies.

Again that figure sounds a bit off. I believe Paul Roark of mono digital

That contrast range sounds plausible but I've never seen that with 1 coat.
