Hi Torn!
Adding to what ElMaestro said my two cents: Maybe you can point out (in a polite way I’m not an expert in) that if one increases the sample size sooner or later any study will show a significant difference if the ratio is not exactly (!) 1. See this post. I don’t know your CV and sample size, but the sponsor cannot be blamed to have performed a study in “too” many subjects (I would avoid the term overpowered).
Horatio: He waxes desperate with imagination.
Marcellus: Let’s follow. ’Tis not fit thus to obey him.
Horatio: Have after. To what issue will this come?
Marcellus: Something is rotten in the state of Denmark.
Horatio: Heaven will direct it.
Marcellus: Nay, let’s follow him.
