Okay, built out a hobbit 12/6/2 ranger/barbarian/fighter... wearing nothing.
He has Dodge and Mobility feats.
Dodge is at 6%, but it should be at 7%
1% 4th level Barbarian
1% 6th level Barbarian
Also, I don't have Improved Uncanny Dodge... I thought Barbarians got that at level 5? Or is it 8 like Rogues?
Then I take some Halfling enhancements and get the 3% Improved Dodge
I'm up to 9% Dodge now... all good there...
I take some ranger enhancements, and get the 3% Improved Dodge in the Tempest line... Accept, still at 9% dodge... Uh-oh, problem because they are the same name? Racial and class enhancements usually stack. I reset enhancements, tried the ranger line first, 9%... Added hobbit Improved Dodge, still at 9%.
So I guess they don't stack... This WAI?
