It does translate genetically per clutch, but not as you say. Genetics do not apply exponentially for each consecutive egg (which form a clutch). Each egg has a 1:4 odds of being a BEL on it's own merit independant of any other egg in the clutch. If my first 3 eggs were normals, do my odds increase that the 4th is going to be a BEL? No- it's still 1:4 for the 4th egg and any egg thereafter.

There is a 25% odd that I will get all BEL's from any clutch- taking each egg into account individually just as you say it applies above. It's not a 25% odd of getting one BEL out of a clutch of 4- it's a 25% odd of getting all BEL's as each egg has a 1:4 odd on it's own merit independant of any other egg.

Again, no matter how much you'd like to deny it, each egg has it's own odds and is not in any fashion dependant on what was produced from any other egg. You cannot apply statistics, probabilities and guestimating to hard genetic facts. As I said before- the sperm are not lining up in front of the egg's deciding on who's jumping in to even the clutch's odds.
