Shuck Vs Emerging Dun

When I posted the emerger pictures the other day and mentioned tying the longer thorax to suggest the separation between emerging dun and nymph, it was met with some interesting, positive comments. I think an emerger pattern should be representing the dun 'wiggling' from the shuck - therefore allowing (and asking) for a slightly larger than average fly. Certainly larger than the usual size you'd choose for the dun imitation.

You hear lots of people talk of fish nailing big, oversized Klinkhamer patterns. Could that be the reason? Nymph + Dun = Big?

Here are a few with abdomen tied to strictly represent the nymph body:
