Pg. 173 of my copy, Adjusting Character Wealth by Level
25% for first feat, okay, that's solid
Then
Up to 50% for multiple feats... that's got some room for interpretation
Is it
A- (IIRC 5) "There are 5 crafting feats, as you take them you get closer to 50%, needing all 5 to get the full 50%" (and if so, what % WBL at what number of feats? 25%/4 for that last 25%? 10% for 2nd 5% for 3-5%? GMs call?)
Or is it
B- "You have two crafting feats, thus multiple, you immediately move the full "up to", congrats on maxing your WBL bonus, the remaning 3 have no effect on it for you anymore" [seems harsh on dedicated crafters but certainly simpler, hence why I hope this is what RAW means]
Or is it
C- Paizo has no stance, GMs call (as PFS doesn't deal with it at all)
I'm assuming B
I'm wondering if this is FAQ/errata worthy, but I figure if it is people will click it, if it's not someone will know the RAW for A or B over the other.
C.
As a guideline, allowing a crafting PC to exceed the Character Wealth by Level guidelines by about 25% is fair, or even up to 50% if the PC has multiple crafting feats.
These are guidelines for GMs. Not hard and fast rules. As such they are always the GM's call.

But if you want a sliding scale, how about this one where the first is the number of crafting feats and the second is the % increase above the Character Wealth by Level:
1 25%
2 30%
3 35%
4 40%
5 45%
6 50%
