So you did 3 pulls of true 93 and one pull of 91 with 3.5 gal of E85? Which maps did you test? stg 2 91 and which 93? Did you have 93 oct or did you just add E85 to make 93 which would have been 94 by the calculations

Post one from each map...

So if you mixed correctly and put in 3.5 then topped off with 91 to fill the tank and drove it around to mix and all fuel was good you 91 would be higher oct then the 93
94 Octane
% Ethanol is 26.72 or same as E27 if total Gals is 15.70
