. . . but they hit the 1:2 odds that they would get a normal instead of pastel, a normal instead of enchi, need I continue ;-) . . .
While I agree its the under desired of the possibilities, from a purely mathematical standpoint, the odds were clear cut the same no matter what was produced, since every mutation involved had a 50/50 chance of hitting.
We have agreed from the beginning that the mathematical odds are exactly the same for every possible combination. The way the OP started this thread, it would appear that desired possibilities influenced his question. I think that almost all threads/post on this website about odds tend to take the desired possibilities into account.
