Not doable. We lack standarization here and definition of overperforming. I would go for standard map size and continents map. Still, you can easily stomp certain civs into ground if they get a bad start (Iroquis without forest, Polynesia on straight coast, Aztecs without jungle, Inca without hills). There are certain civs that have universal UA (Poland, Celts, India, China, Indonesia) and they aren't always OP, but consistent. And there is more - the sooner you get UA/UI/UB, the easier for you to snowball (as by design it is snowballing game). Thats why Babylon AI always has tech lead, IRQ will have awesome production and Ethiopia will rock faith.
We should at first check which civ isn't rocking in players hands and I think Ottoman is one of them. Or we can just do pure math and Ottomans aren't doing that well in this area either.
