DL and UA have more RJ's than AA. The upper limit seems about the same (looking at the contract comparison). So any increase in AA RJ flying appears to be closing the gap to DL/UA.

How many additonal P&C hrs are being paid by DL's CD? Until we have that data we don't know what the value is AFTER the company adjusts their schedules to minimize CD P&C. DL buddy says the quality of their sequences/pairings went down as the company rescheduled their trips to avoid paying P&C ('soft pay').
