Very improvable. I'd need to bot out 4 1/39 crits, or a lower health value and 4 1/39 crits and 1 1/39 non-crit (for the rival fight.) For the Weedle fight, botting more criticals would be a good idea, but I don't know how to do anything with Lua, nor do I know how to put the different actions in a route script.
