Weight is a number don't compare your BP to other BP just make sure that you feed a prey equal the girth size once a week or every 5 days if you feel like you need to. Honestly if it's a male and it is a pet I would stick with once a week.

What is important is that the animal looks healthy and well proportionate the rest again is a number and a lot of things come into it, such as weight out of the egg, how fast the animal was started, how reliable of a feeder the animal is, prey size, frequency etc.

I don't weigh my animals unless it is for comparison purposes of how a morph age based on size or at customer request, it's all by look and feel here
