I deliberately develop to a lowish contrast and find that VC papers behave better at medium to slightly higher contrast settings.

I should add that developing to a lower contrast makes the stain less extreme, and so avoids to some extent the drop in contrast in highlights that can be a problem when staining is very strong. I am sure that I'm still benefiting from the stain, though.
