Phoenix Rising, that chart shows that way because breeders need adult sized snakes to breed so a breeders feed schedule can be more often to get the animal to grow faster.

Personally I don't believe in feeding more than once a week, for any of my snakes regardless on whether they're going to be breeders or not. And it seems as though most of the community here agrees as well, this chart is otherwise a good guideline to food sizes for a snake as it grows.
