Assuming you mean "stats", rather than your suggestion, I'd recommend just adding a link to the appropriate stats thread for the particular environment from the recommended decks section. Including actual stats gets into huge issues about updating the posts and the age of the stats. Would they get updated every time somebody does 50 more runs? Would they get updated once a patch? What happens when the community recommended decks OP doesn't get updated for a while?
My general rule is that you should only update a given thing once if at all possible, and just having a link to the active stats thread(s) accomplishes this. I certainly think having some stats available in the recommended-decks thread is a good idea, particularly since some of the recommended decks are actually pretty much terrible (relatively speaking, at least) at the moment.
edit: Ah, if we include "when last updated" it becomes a bit less of a problem, but I still support just linking to the combined stats threads in most cases.
