On the first point, the Acrobatics description says "For a running jump, the result of your Acrobatics check indicates the distance travelled in the jump (and if the check fails, the distance at which you actually land and fall prone). Halve this result for a standing long jump to determine where you land."
So for starters, I guess "the result indicates distance travelled" would mean 1pt rolled = 1 foot travelled? Is it just saying to look at the charts? What's with the line about halving the result for a standing long jumps then? Do you double the DC (per the main description) AND halve the result? That seems insane. I feel like I'm failing reading comprehension and missing something major whenever I look at this description.
My main question though, is does this apply to a running high jump? There's nothing saying it doesn't, but it seems odd that long jump and high jump distances would be the same.
Edit: Okay I think I've answered my question here. It's just referring to the same thing as the main description in a slightly different way, yeah? It's confusing, but that seems to make the most sense.
Third: For the purposes of the "faster base movement" bonus to jumps, does fast movement's enhancement bonus to speed count as part of the total "base" land speed, or is the creature's unmodified land speed being referred to?
