In high school, refs should never be making double contact calls on the first touch of each possession. Every time a team gets a new set of 3 hits, the rules prohibit calling a double contact on the first of the 3 touches, no matter how ugly. A lift can still be called, though.
I do agree the calls on the 2nd and 3rd touches are incredibly inconsistent. However, in 15+ years of volleyball, as a player and a coach, my experience is that refs generally are not inconsistent between 2 teams playing each other, but refs are inconsistent between each other. Some refs call nothing, some call everything.
