19.5-20ma is on the low side of things, but as Liquids mentioned, that doesn't necessarily mean anything in regards to the V4.
These amps run the tubes hard, and running the bias cool isn't a bad idea. typically I tend to see tubes bias up anywhere from 19-26ma in a stock V4. so you're in that range.
you could increase it a little if you want... might be an interesting experiment for you.
