Answers:
I'm sorry, I have to disqualify myself, all 10 cakes I baked to prove out your theoretical question where white, but one thing I did notice was that in test g was I came up with a great recipe for Yogurt. In #8 the equilibrium moisture content had a great effect on the texture with the addition of lemon to the soda which reverts back to g, adding a possible curd resulting in higher moisture content.
