Only from when it was introduced. Also you get a point for Best AVNSC in your Group if on group system, or BAVNSC if not on group system, so you don't need breed classes.
A minimum of five points have to be won by getting placed in the group so it can't be won by dogs getting BOB of one at 25 shows, so not an easy award at all.
It is like an Open show Champion, (but wins at champ shows without CCs don't count).
The fastest way to get the awrd woudl be to win Best in Show, and the group at two shows, and then the group at another.
