Fraction/Formula for saving throws that are neither good nor bad.

[Zoatebix]

I really like the fractional bonus system from Unearthed Arcana, and I'd like to use said rule in a game with some classes with saving throws that go up to +9 over 20 levels, but it's way too late at night for me to be extrapolating formula from said saving throw progressions.

The +9 over 20 level progression from Monte Cook's Arcana Unearthed don't seem to follow a linear formula like the "good" and "bad" saves do (level/2 +2 and level/3 respectively) - but they do follow a regular pattern. Am I just sleep deprived and missing something, or do they not follow a formula that's easily reduced to a fractional bonus for a given level?

Does anyone have a good idea of a formula to use for a "middle" save? Should I just add 1/2 a save bonus for some levels and 1/3 a save bonus for other levels, like Monte's pattern seems to do?

Level*5/12+1 is the "average" of the two PHB formulas, but that definately doesn't work out the same way. +.45 per level doesn't seem to work either, unless you add a constant to make second level a bonus of +1...

Stumped for now.

I don't know about monte's, but the middle one in d20 modern is regular and predictable. (Sorry, I'm sick and don't feel like trudging downstairs to get my copy.)

The one in d20 modern is a little tricky because it's ALMOST .4*level+1, BUT NOT QUITE. But you can get it by 1.2+.4*level (dropping fractions, naturally).

Thanks! I didn't think to pull up my Modern SRD...

Anyways, after a full night's sleep and some monkeying around in Excell, I figured out that the Unearthed Arcana middle save bonuses can be replicated with 0.5+0.43*level.

That's pretty sloppy work though. I'll come back with something better...
