weight helps but you do have to take into account 18th century tolerances were not as good as they are today so the weight can vary around o.1 gram for early re-strikes. As for diameter.....its not that helpful unless the diameter is ridiculously out of sync. The MTT was struck with out a collar...also with screw presses the striking pressure could vary these two factors can see coins(from that era) can varying (40-42 mm)

I acknowledge your points, but from the serious researcher's standpoint, I'd contend it's still worthwhile compiling this data to establish ranges and means for different varieties.
