This is just gibberish.
No its not. By perfect selection in one generation I was referring to total selection against all the other types in one generation. Which is what you did in your Monkey scenario. Your selection coefficient was 1.
"Denoted as s, the selection coefficient is a number between zero and one. If s = 1, selection against the genotype is total, and it makes no contribution to the next generation." https://www.blackwellpublishing.com/ridley/a-z/Selection_coefficient.asp
As I said before: To have perfect selection in one generation, you had to pay the price of the elimination of the other 9,999 in that same generation (destroying your population) for the evolutionary scenario to work. Your example tried to have the benefit of perfect selection, without the price. There is a cost to selective replacement that must must be paid. In this case the cost in the real world would indeed be the lives of the other 9,999. I was simply showing that an evolutionists own "rosy example scenario" when adjusted for reality runs into trouble.
