I assume this chart is base on you experience? So how many BP have you fed base on this chart? Especially adults fed xl rats?
I guess I am one of those sheepI eyeball it it and never feed anything bigger than a 120 grams even to the largest of my BP.
Based on your chart and my experience I can guaranty that those fed xl rats will fast, personally I prefer animals that eat with consistency.
There are many ways to do a lot of thing and if this is what you want to do itīs fine whatever works for you (does that mean thatīs what they SHOULD be fed???).
Itīs lot more food then they really need not to mention the risks associated with feeding an oversized prey.
