Your post says "What's with the trunk?"
This analogy would give a (reasonably) conservative expectation, say body/trunk ratio for a skinny elephant would be about 10/1, i.e. if the drills hit a few more holes with 50m @ 10gpt in the SE then this expectation would give another 40 Moz (that's a nice number). But if I spell out that kind of number then quite a few posters would be all over my post asking for proofs or tearing it apart (and suiters would be all over PRB).
Just magine what would happen with your "tail and body" analogy.
