I've noticed the problem around here is there are a lot of know it all's, they have snakes,they know what works for them and they think that's the only answer. Well it's problem around here if u disaree with them and that's not what a forum is about...anyway,back on topic...and good point about the meal thing,as breakfast is most important meal and dinner shouldn't be the largest.
as for the chart I'd say it's accurate and exactly how it's gone for me,so to the OP,good thread and very accurate chart. I don't use weight for my rodents and feed according to the snakes fattest part of his body..but his prey size and weight lines up with your chart.
great job
