That's CALULATED ODDS, you used the word QUANTIFIED.

I believe you can figure out someone's EV based on enough long-term results. If someone has been picking 57% on 50/50 chances over thousands of trials, I would say you can be fairly confident they have an Advantage and you can calculate/quantify it within reason.
