Interesting take on AFR, but it assumes a linear relationship between fuel reduction and water mixtures added. I wouldn't be so sure about this one.

Yes, and that's what I told to calculate. Now get the calculator and check how much replacing 1.5% of air with fluid (roughly, assuming about 20% of fuel injected water) changes your air to fluid ratio in a 12.5:1 air to fluid mixture ... Changing 1.5% of the air with water doesn't make the air to fluid ratio to 10:1, at least according to my calculator
