What is the growth rate ov Male Ball Pythons?

Sometimes grow in length faster than girth for awhile, it will all catch up. Hes not going to get bigger than 4-5 feet or so, I use a scale and a log book, I keep logs on meals, sheds, and weight. I have an 05' normal that weighs 896 grams, has never eaten anything but live rats, and hasn't missed a meal yet.
