For sake of discussion, assume that ALL food is peppered, ie take pepper out of the equation. That still makes mixing MBC, BBC and CC superior than just eating MBC, in terms of milk use efficiency. And yeah, it's for really high stats, but same principles apply for lower stats if you're using food with lower base FEPs.
As for making beer, a barrel of it takes very little effort and can last you a long time. The cost of beer in Bierwurst is negligible. Pepper wise, I don't think that making food that beats BBC is a waste of two drupes, especially once you get into high meat quantities and pork is essentially free. Seriously, at high meat quantities nothing beats domestic animals when it comes to payout for effort invested.
And you can easily shave off like half the FEP bar with reduction if you mix food at high levels. Just use low FEP foods for that, shit like carrots, peas, chants etc. Getting 250 FEPs is a lot easier than getting 500.
And I do smoke ~q200 hemp, I just forgot about it
I just thought you'd be eating apple pies since you hate multi-FEP food with a burning passion.
Bottomline, yeah, you have higher stats than me, but that's because you play like 8 hours a day and I play half an hour. I bet I have a better stat/food eaten ratio, though.
