Does this math work?

[incognito]

I usually put 4 bloodhunters (priests with SDW as Mictlan) in a province, although everything I read says other's stick with no more than 3. Anyone figured this out for fact ie that 3 is the best return for the gold?

FWIW, I also set taxes to 0 and have a patroller w/around 30 slaves mopping up unrest. Is there a better plan to be had? Something that will allow me to have unparalleled blood income and maybe keep a little gold?

Lastly, I almost always watchtower/lab/temple each province. No sense getting your bloodhunters wiped out by raiders..., but am open to other ideas.

Thoughts appreciated, especially concerning MP strategies here.
