Blob, tbf, I wouldn't have expected DK's response either, but just b/c you or I would never do something like that (and tbf I can't say that for sure about myself), doesn't mean it can't possibly be true for others.
Anyway thanks for the reply DK, and I understand what you're saying about the "true" skill jump being different from the "perceived" skill jump. I just don't think people realize how much the perceived jump gets in the way of them accurately discussing the true skill jump. When people say "25nl is sooooo much harder than 10nl - the regs are way more intense," I see a whole lotta perception. When they begin to say "25nl is much harder than 10nl, because there are more regs, the regs are more aggressive pre and post, and even the fish are playing back at you postflop sometimes," then I pay attention.
