In the first PD simulation I made with five strategies which I got from my friends I applied such a model, albeit with random mutations rather than division of descendants into thirds. The results were not as interesting as I had expected. Only one strategy showed non-trivial optimum (it was basically TfT but defect after turn n and the population made a sort of gaussian distribution around n=85). All other strategies ended up with extremal (and quite obvious) values of the parameter.

This is the pearl of interestingness.
If you are interested in that tournament, the graphs are here, you can use google translator to make some sense of the text.
