My ball normally sheds every 6 weeks or so until this last shed. She last shed on the first of October and, as of this morning, has not started to yet. Also my boa (younger male) and her were shedding at the exact same time, every time, since I brought him home, in April. He completed his shed last weekend so I assumed that the ball would be any day too but not so. She has grown quite a bit and, perhaps, her shed cycle is slowing down somewhat from her younger days (now that she is an old dolly of roughly 2 1/2 - 3 yrs).
