Hear, hear ! And the corollary is that there is usually no one right way of
doing it.

I blow dry to stop the sensitiser sinking too far into the paper.

No, that is one ml of sensitiser on sized hot pressed paper. The trick is
getting the sensitiser to sit where you want it to by a combination of drying
and humidification techniques which I went into during the 'blow your socks off
debate'. Eddie Ephraums says that he can do it in 0.5 ml. I get a full range of
tones. There is a 20 x 16 in the Paris video that may give an indication. One of
the prints on the video accommodates a brightness range of six and a half stops
and another has eight stops.
These are techniques that I developed after Peter Marshall's and my first
explorations of pt/pd printing some years ago, but even then I do not remember
us concluding that double coating was the best way. That would go right against
my cost effectiveness programming and give me pains in my diodes.

Yes, the secret is in the negative.
