I think the swings in itself are standard.Losing 200 BB or a little more is not uncommon. But to lose 380BB in 9K hands is insane and so are also winning 480 BB in 8K hands IMO.
Your idea is great though. We should take this graph and a couple more from other players and save them to show both what can happen in extreme cases and what size on downswings one can expect playing shorthanded.
