As far as the "Divine" rap you are stating that there are piles of evidence about 5th level being the best for our modern society.... In all the years I have been playing D&D and now Pathfinder (36 years almost 37) I have never heard or seen these piles of evidence in which you speak. Gandalf, being a myth himself, was not 5th level for certain. Throughout history one could name figures that would be in the 19th to 20th level range. Through Myth or Real life.
You probably weren't looking. It really depends on how you view deific power. A lot of common consensus is to slap the abrahamic "all mighty, all powerful and infallible" onto any concept of the divine. I disagree, myself; elsewise, how could Zeus have overthrown the titans? Or the aesir beat back the jotun?
The 5th level cap was a breakdown done in an essay, showing that a 5th level theoretical physicist could occasionally hit DC 30 and answer questions no one has thought to ask before. "
Gandalf was a 5th level Magic-User" is an article from an old dragon magazine (I can find a link if you'd like) which, while canonically wrong, jives with my personal belief of "don't slap 20 levels on someone who's the best in their field". I prefer scaling down, so each +1 is a vast and note-worthy improvement. It's all preference here, really.
Simply stating there are piles of evidence without backing it up is just words sir.
You're right, and I apologize. I made a blunder, there, and figured the essay or article were common knowledge- the odds of knowing of at least one were, I thought, pretty good. I also didn't supply links because I was lazy, and it was late.

As for the fumble table, it's a good one, almost. The very end, where there's that one percent chance of auto-crit max damage to yourself, AND landing prone? Most of BaB should reflect poise, intuition, timing, and distance. When you can gauge millimeters at a glance, and stay far enough away from enemy swings to lose an eyelash then jump back into the opening they leave, you shouldn't be able to fall onto the business end of a weapon that badly. The save DCs are a nice touch, and help to make it more fair. But wouldn't a self-attack work better than "try to roll away from the tip of the weapon they'd pointing at you"? I'd feel better with it meshing with the rules more; say, they drop the sword, fall prone, and the weapon acts like a spike trap. Seems more constant to me.
Again though, I have never personally seen a game (played, DM'd or watched/heard about) where the fumble rules were fair to the players at all. I know it's anecdotal, but it sticks to me, y'know?
