I don't abide by requests to please someone who is too much of an asshole to acknowledge that someone who disagrees with them might have something productive to say and who thusly insists that I stay out of their pet thread for fear that I might have something to say.You can voice your dislike of something based on preference and that's totally fine. Even if it wasn't, it's not like you'd abide by the request (as you haven't in other threads). Aside from some minor nitpicks about the check DC setup and other stuff, you're just complaining about the way he's gone about meeting the goals of this tweak without offering rationales that matter to the rest of us or alternatives that could be much better. I'm not convinced that the growth he's got here is the only or best way to do it, but it does make the skill remain useful over all levels and ranks. If you really think you can hit the two design goals without also making mundane jumping irrelevant after level 5, then do it. Contribute an alternate solution that doesn't make your eyes bleed or strain your comprehension.
Requests that those who are not interested in a particular idea (such as asking those not interested in wizards to not comment on your archmage prestige class) actually make sense and are treated as such.
So, a proposed solution: Make level 1 characters make jumps that are based on what normal people can do (not Olympic atheletes) and drop the spells making the skill meaningless if it is so much better to use fly (despite that being limited in how many times and how long you can do it per day regardless of how tired or rested you are) over a moat than Jump.
But hey, apparently "a worthwhile way of getting around, and not a waste of skill points" means that we have to ignore the fact spells make skill points a waste after a while because magic does everything almost damn skill in the game does and does it better, though Diplomacy probably beats any charm spell.
If you want Jump to be a useful skill, it needs to compare to other skills, just as Weapon Focus: Longsword has to compare to Cleave, not to mage armor.
