I assume this is what the gnubg benchmark stuff is about btw? Comparing probability estimates in a bunch of benchmark board positions against rolled-out probabilities? How do you condense the many different cases into a single number - ie sum( weight * difference^2 ) - how do you relatively weight the different benchmark positions?

The gnubg benchmark database has the resulting position and rollouts of that for each possible move in given position. The net selects the best move, and the there is a error rate on each move. So, we don't care about the exactness of the absolute evaluation, we care about the relative evaluation between the moves (or resulting positions after each move). That is what makes it select good moves!
