It depends on how bad my troop losses are from week to week. I try to always keep enough troops on hand to fight the entire Spire and get 4k-5k points in the tournament. And since my troop buildings are never idle, I tend to only need to run the Brown Bear once a month? And when I do, I am more restricted by my amount of time boosters for how many troops I make, than by anything else, because I prioritize bossters first for completing guest race-related stuff. Because of that, I tend to only make enough when the Brown Bear is fed to cover a few weeks of fighting. Because of all that, I almost never go higher than about 100 squads of everything.
