And it's the interpretation to which I'm, on balance, now inclining.
Sorry I can't be of more help; whereas I have a collection of Thucydidean editions and commentaries on which I can draw, I've nothing for Polybius. Perhaps more importantly, not having read any Polybius (beyond your extracts), I don't have a feel for his style or idiomatic range. Both these factors, I'm afraid, severely limit my ability to assist. I can't remember whether you have access to Walbank's commentary, and I don't know whether he comments on this point.
Best wishes,
John
