It's been a while since I was mining seriously: what's the average number of chunks you can mine per earthshaker? And how many energy does it require to mine? I know that both answers vary with your level of mining.
I really am looking for the average number on the chunks - I know that if you come across a dozen rocks in a row, that's faster than having to walk, and that it's worthwhile to pass over dullite if you're looking for sparkly, etc.
Likewise, I'm wondering about the numbers on grinding with a flaming humbaba - I remember that being a shorter buff, but that I'd use up a Grand Ol' with each one, since the energy was considered at the beginning of the buff. So, 2,000 chunks, right? How much energy is that per chunk?
