VVR QUESTION - bias tracking in an Express-style amp

[Curbdog]

I have installed Dana's VVR in my Express-style amp, regulating the power section only, and have installed a post PI master volume. I have external bias points on this amp, and have biased the amp correctly at maximum voltage. As I turn the voltage down with the VVR, I notice that the bias in milliamps increases. I know the bias is supposed to "track" with the voltage. I just want to make sure that I am seeing the right thing, and that it is going in the right direction. It sounds right, and the plates aren't going red at all, so I figure that is a good thing, but I would appreciate any feedback. Thank you.
