Not sure if someone's done this already, but here's a spreadsheet to automate all your monster math. Just input the level, organization, and role of your monster, and you'll get the EV and stamina.

Hope this is useful!

Spreadsheet for automated monster/retainer math

I think that works?

Good catch, thx! Updated.
