7 days sounds good for a 360g BP in my opinion. I have snakes on either end of that scale. My pastel is around 260g empty and my het albino boy is around 550g empty and both are on a 7 day schedule. For a 360 I would be on small weanlings which vary in weight from around 26g to 50g. Are you planning on feeding Frozen thawed? If so you could ask the supplier to give you some of the larger small weanlings so that you're not feeding too little. I think (although I may be wrong) that a small rat is too big for a 360g BP. My 550g boy is only on large weanlings (between 51-80g according to a comparison site I found online)

Here is the link I got that information from, the weights of course aren't set in stone but give a good rough guideline:

As I said if you are feeding F/T you can ask the supplier to weigh the food and even ask what they might suggest if you are buying in hand and not online. If he is eating the small rat though I may be wrong, not sure if you are asking in advance or if this is what the BP is already eating?

Hope I've helped a little bit, this is just from my very short experience! Trust me you get used to it very quickly though and soon you will forget what it was like before you had your BP. Good luck
