In all other parts of the eidolon, AC Evolution points etc etc, it says either "This is the base total" or "Total number." However, with Str/Dex Bonus it just says:
"Add this modifier to the eidolon’s Strength and Dexterity scores, as determined by its base form. Some options available through the eidolon’s evolution pool might modify these scores."
So my question is how is it added? If you have a Quadruped the base Str and DEX are 14. If I make a level 5 Quadruped are its stats 16 each, adding the plus 2 for 5th level, or 19?(+1 for level 2, +1 for level 3, +1 for level 4, +2 for level 5)
Nothing says that that number is the base plus and nothing I have found says it does not stack.
