So, it fails solo cooking games half the time. No plugins enabled. The bot will be stuck on the boat "fighting fires" and not move. When it does work for solo cooking it gets 7 permits, which is fine but its possible to get 10+ if it would try going for 3 rounds.
Perhaps with Dragon Harpoon or the humidify setting success is guaranteed but for low levels without these things, using 10 buckets and spirit anglers with 17 slots free, I am getting the above result.
The trial should give you a decent idea of success rates with your stats.
If I get time I'll see if there's other strats that have higher success with lower fish chance (likely at the cost of exp and rewards)
