Purely from a statistical vantage, one would assume a normal distribution of the samples with half of the samples above and half below the mean.

Exactly.

I think the benchresters should use a shot group's mean radius instead of extreme spread, especially for aggregates which would be the mean radius for all shots fired. Extreme spread's the worst way to measure accuracy as far as how close the shots are to group center when several groups' sizes are averaged for score. But that would take a while to do at each match. If it was done on old targets already fired, some of those record holders based on extreme spreads would no longer claim the prize.
