Clearly you're still making an assumption because e85 is not always 85% and e10 is not always 10%. I filled my car last week with 15.5 gallons of e85 and my flex sensor was reading 79% Ethanol. Prior I was at 60%, so I had a very small % of 92 oct in my car at the time. Too little to drop the e85 from 85% to 79%. So to be clear, you'll never get 50/50, but does it really matter?

to get E50 on a 16 gallon tank its more like 8.5 gallons of E85 and 7.5 gallons of Pump 91 or 93, based upon regular pump having E10.
50/50 - E85/9x Octane is more like E48.... just saying..
