naturally ball pythons are not on a consistent, weekly feeding schedule and maybe eat a handful of times a year. eventually they will grow to their full size potential but obviously it would take much longer for a wild bp to get there than a captive one. if one were to acquire a young bp that was fed monthly for a year or so and then place it on a weekly feeding schedule, i think that this animal would be able to achieve its potential size, or close to it, regardless of its feeding history.
