Also, on the topic of Nobody Dies, I am now imagining that if we send a girl over to help teach Nagoya how to do RT Crop Rotation then she would be aghast at them when they opine that not being hardline about no casualty chance will give them better manpower returns. Because nobody has to die, and they boggle at the sheer naivety of the girl who was going into such depth regarding how to best kill demons for maximum cube return.
Pondering some numbers on Nagoya's hunting habits now.
With their territory size of about 450, and using nothing but solo hunters, and assuming 4 elites are dedicated to it (leaving remaining elites to other stuff), they would need
85 vets on hunting.
If they're not quite as heavily invested in hunter safety (ie: no cell phones or shields, but all the rest of our normal training, full kevlar, plus dispatch), their casualty reduction for solos is 6%. If they hunt to exactly DS 0, that gives them a 3% casualty rate per month, which is 1.275 deaths per month. Elites are well below 0% casualty rates.
If they then did a test run of rotating tactics, taking DS up to only +5, they'd need to use 2 elites and 60 vets. It would raise elite casualty rates to 0.5%, and vet casualty rates to 10.5%. A 1 in 200 chance of an elite death, and 3.15 vet deaths (plus another 0.6375 from the non-overhunted side, for a total of 3.79 deaths per month).
Switching the overhunting side to pair hunting for the vets drops their casualty rate to 1.5%, which 0.56 deaths per month, or 1.2 deaths when combined with the non-overhunted territory. Doing so would require 75 vet hunters for overhunting, instead of 60, though. That's about the same total death rate as their normal hunting methods, but requires 32.5 more hunters to gain 85 more cubes.
Once things start cycling with both an overhunt and an underhunt, cubes per month is 475 instead of 450. Total vets (using pairs on the overhunt) goes up by 21. Death rate is 1.4 per month.
This assumes no greens are hunting, which is likely a faulty assumption. If greens don't hunt, they take 12 months to reach vet instead of 6, and Nagoya has a history of needing to get people up to vet status quickly. Putting a number on how many greens are hunting, though, would be blind guesswork, so I'll skip it.
Anyway, it is not unlikely that Nagoya treats 1 hunting death per month as completely normal, with 2 deaths as uncommon, but not rare. With hundreds of members, 1 or 2 deaths is a drop in the bucket.
If they are conservative on cube usage, and only allow 1 cube on spirals, they will likely have 11 to 14 deaths per month from spirals (assuming a total population of 350 meguca), at 1 to 2 morale. At 2 cubes, that becomes 5 to 7. That's a cost of 22 to 28 cubes per month when using 1 cube, or 33 to 42 cubes when using 2.
With any of those spiral death rates, the hunting death rates are pretty minor, and I can see them being skeptical of our insistence on safer procedures.
With full safety, it would cost them 120 vets to hunt up to +10, instead of the former 85 (again, ignoring any greens). Of course, it gets them 505 cubes. Still, it's a 17% loss in meguca efficiency, and with their numbers, 17% is a lot.
If they refused to worry about the death risks, they could go back to using solos (97 total) for only a 1% loss in efficiency, but accepting 3.4 deaths per month. An extra 2 deaths per month in order to save 23 units on hunting duty and gain 55 cubes.
If they didn't bother adding the extra safety stuff (shields and cell phones, mainly), it would be 5.8 deaths per month. I'm pretty sure they'd put in that effort, since it's only a bit of money.
Overall, that's what I'd expect to see from Nagoya using rotating tactics (though using greens would change the totals by quite a bit). And I'm pretty sure they wouldn't see it as worthwhile to switch to a "no one dies" setup. 20 more units available for work per month beats out worrying about 2 or 3 extra deaths.
