Thanks you both!
@MagicManICT: i dont get the calculation example on this FEP side.
It says:
"Joe has 15 in all attributes. So he needs 15 FEPs to get his next attribute increase. He eats enough bear meat to give him 10.5 Strength FEPs, and his Strength goes up by one. Wait, he needed a total of 15 FEP's didn't he? This is an example of the "variety bonus" that's applied to eating. The first item he eats reduces his required FEP's by 30%, to 10.5 from 15. Because he ate only STR giving FEP's, his STR went up to 16. "
and FEP Redution per unique item:
0.632 ∗ \sqrt(MAX)
i wonder:
If i need 15 FEP and eat an item with 10.5 FEP its 15 - 10.5 - 2,45 (the FEP Reduction) and this wont be enough for the increase or do i understand something wrong?
