I wouldn't feed my snakes anything that will leave an impressive lump for 5 days.
And this may or may not pertain to your snake in particular, but I really don't know where or when people started thinking their snakes should be a certain weight/size. Unless it is noticeably skinny, it should be the size it is. Some snakes metabolize and transfer the metabolic energy into growth at a much faster rate than others. I have 5 2010's, ranging from 550-1,800 grams, and not one is underfed, "too small", or should be any bigger.
