I think the version of software on the console dictates whether it'll hit 0% or not.
I've never heard that, the 15's had dry bias issue below 10%, remember?
Hell Randy, I can't remember what was for dinner last night. Not saying the 15 didn't, I honestly don't recall.
As far as the 0%, this is for the Vue console, didn't look at the VP2. See version 2.14.
