The reason I didn't quote more is that I didn't bother reading more.
The opening equation was based on a misconception, and so everything
after that was fallacious. Indeed, from what you say above, you never
abandoned the equation itself, but merely concluded that the
assumption of constant European admixture couldn't be correct.
However, the problem was the equation, not the assumption, because the
assumption eventually *will be* correct -- the admixture proportion is
asymptotically approaching a steady state. The point is that complete
replacement is not something to find a "way out of", since it was
never in prospect in the first place.
