Right now I'm working on figuring out turkey formula. It would seem like the coop purity matters far far more than turkey purity, as two 20% pure turkeys produce a 6% pure egg when the coop is 2% pure.
I've tried many things, from calculating the turkeys and coop average, with different weightings for the coop such as (t1 + t2 + coop)/5
Then I tried (cube of t1 X cube of t2 X cube of coop)^3 and then sum of cubes to the 3rd power, and neither of those worked either.
Any ideas?
