A really, really modest proposal
My quibbles with the CAPS incentive structure run very, very deep. Given management resistance to my many critiques, I shall start with a simple, transparently correct suggestion to improve the system: axe the twenty-minute change-my-mind period.
Currently, anyone can game the system for twenty minutes of price action, and cancel if wrong. A free twenty minutes times 200 possible picks -- I wager dollars to donuts someone out there, probably one of the more "successful" players, is already doing it.
There is a "yes I'm sure" button for a reason. Put the best scores above suspicion.
