People here often say that women go for the top 20% of men. I agree with this, but what happens if the genders are skewed and no longer 50/50?

For example, if we have 100 men and 100 women, the top 20 out of those 100 will have 80% of the sex. But what if the ratio is 60/40?

Then, it would be 100 women to 66 men. This makes all of those men significantly more attractive, but how much? Would the top 20 of those 66 then be the chads, or perhaps even more of them would due to the desperateness of the females?
