Reid vapor pressure only comes into the equation when we talk about converting to straight ethanol.
Uh no, that is incorrect.

The Impacts of Ethanol and alkylates on Gasoline Volatility
? C-8 alkylates boil higher than the current T50 of California gasoline, thus, their increased use will lead to higher T50, and the associated problems
? Ethanol does not blend ideally with gasoline with respect to volatility. i. e. it does not follow the Clausius-Clapeyron behavior
? Ethanol raises RVP, and depresses T50, but not the DI, which is related to engine performance
? The polarity of ethanol may lead to increased permeation of fuel compounds through plastics and elastomers in the fuel system
? Ethanol, reduces T50, but not DI, and its impact on RVP will lead to higher evaporative emissions. Permeation needs to be studied further, but available data suggest a need for concern.
Hot fuel handling can be managed, but only if the proper parameters are controlled.

"Check my profile and my location. I do know something about the ethanol industry."
By that reasoning someone born on the sand dunes of Kitty Hawk must be an aeronautical engineer, correct?
Uh no, that is incorrect.
