can see where your coming from , but P100 was 98 RON petrol with 10% ethanol.
United E85 is actually E85 and people have tested it closer to E90. The 105 ron may be the minimum rating they give it as I think E85 can actually be as low as E65 or E70 and still qualify as "E85" like caltex E-flex.
Depending on where you read ethanol is quoted at 113 RON

I have tried adding the 10-12% E85 to 98RON (non-ethanol) and seems to perform similar to P100.
