I understand it's off-topic, but this situation is extremely rare, in my opinion. There need to be a lot of coincidences for someone to have 150 companions on the second map... I've been playing for a long time and haven't come close to that, only once did I have around 150 companions on the second map =).
It's been said that it's approximate. If there's such a generous distribution, then it's worth using it to the maximum (in the maximum difficulty setting)...
