What summoner level would you be considered to be for the purposes of Evolved Companion for the purposes of evolutions that are affected by summoner level (ie Resistance or Magic Attacks)?
I don't see any reference in the feat itself. I'd imagine you'd go off of your level, but since none is listed it's equally as valid to rule that you have no Summoner levels.
Since this can't be for PFS, I'd just talk it over with your GM.
