Over the long term my odds per clutch have actually been a little better than normal. I've rarely hatched a single clutch that matched the odds though. I usually get a really good clutch or a not so good one. I have had clutches from an albino to het that didn't produce any visuals, and I have had some that produce almost all visuals.

I've actually had very good luck with possible hets, over the last 5 years I have bred 23 possible hets that were mostly 50%'s and of them 18 have proven out. But most of them I had produced myself, so I knew for sure they were actual possible hets. The breeder you get your hets from really matters, I have several "100% hets" from TSE that proved out to not be hets.
