I’ve been to Kuche. There was never anywhere close to 40 hunters. I would say the average was 10 hunters while I was there. Maybe less.If there was ever an example of the phrase grasping at straws this is it. Comparing an early 1900s safari in east Africa to a hunt factory in Limpopo is a ridiculous comparison. The number of hunters in camp during old East African safaris would have only been a handful of friends at most and several professional hunters, never 40 individual hunters. There would have been a separation between hunters and staff same as there is today. However, if you want to use it as an example as you did the math at kuche would be significantly more than 40.
Hunters (40) + PHs (30) + Trackers (30) + Camp Staff (10 minimum) + Skinners (10 minimum) = 120 minimum during a peak week. If their in house taxidermy and dip and pack service is on site the number goes up even more.
So no, all your math is wrong. There was never more than 40 people total at camp.
