So regression to the mean mostly effects the first generation. Also, I should have skewed by 70% heritability. 100 + (130 - 100) × .7 / 2 = 110. What factor is missed in this first generation, or included in the next for regression? 110 + (130 - 110) × .7 /2 = 117.

Why? Or how? or do I have this right? Ex, If 130s men mate with 100 average women, then we have a regression to 100, assuming heritability of .7, we get a new mean of 110. If the next generation does the same, is the regression to the new mean of 110?

My example and Jonatan's are fundamentally different in that I'm positing severely selective mating (not just assortative mating) and therefore the regression effects will mostly be seen once the selection is removed and the population mates randomly amongst themselves.

I think your example is equivalent to my planet settling example, eg simulation 5.

It becomes that in what is effectively the F2 generation but what I'm doing before that are several backcross generations.

Like a new planet every generation.
