All I was saying is that 50% Possible DOUBLE Hets would insinuate that you had a 50% chance to have a DOUBLE Het snake, which is not the case, it's actually only a 25% chance that you have a DOUBLE Het. It's just a matter of how you phrase it, and 50% Chance of a Double Het seems to insinuate that 50% of the snakes will be (statistically) a Double Het.
