Just my opinion from 46 years experience with snakes people shouldn't be too hasty to feed another meal until the snake has digested and excreted the previous meal. This greatly reduces the risk of an intestinal obstruction or the snake getting bound up because that can kill a snake. This way if it passes fine you know the snake isn't having any digestive problems.
Yeah I totally understand that. In the past, I was feeding him one jumbo rat every week but now that I ordered the larger ones from RodentPro, I'll be feeding every other week when he's back on a regular schedule again. Thanks for your words of wisdom hun, it's always nice to hear what other people have found successful 
You're very welcome my friend :O)
I look at it like this digesting is a big process for a snake that's why they lie still to digest food and it takes a lot of their energy to digest another reason they shouldn't be disturbed while digesting food.
Why would someone want to say feed a snake every week so they have to use that energy over and over again to digest when they can reduce the amount of times of feeding the snake by giving it one or more food items in one feeding? It saves the snake some work and the process for two is the same as for one food item they are just working a lot less to get the same benefits in the long run.
