So granted this is totally impractical for multiple reasons but I was checking out the new capstone feats from Ruby Phoenix last night on Nethys and the Investigator one, All the Time in the World, caught my eye. So for 3 actions you can take 9 actions worth of observational and mental actions. Well if you use all 9 of those actions for Reason Rapidly you could make up to 45 recall knowledge checks. And you can do it every round if you wanted to for some reason. Pretty sure 45 actions on a turn reliably is the best action economy though.
