I started testing a mix of 87 e10 e85 and 91 ethanol free

Thus far my lie o-meter reads 60mpg on flat ground when before it topped at about 53mpg on the same stretch but only if my motor is warm, my startup/warmup FE is MUCH lower.

Very odd effect.

My test mix is
50% e10
30% e85
20% 91 e0

The car hops less accelerating during warmup.
