I think that was supposed to be A/1 and A/3 in the last sentence below? But, anyway, I think the question (and it's a good one!) is how, after having drilled down on one of these, eg A/1, would you then still show the counts for the other A/N categories?
Ie the counts would show how many hits the user would see if they changed A/1 drilldown to A/N instead. I call this "drill sideways"...
