There is no math just a prediction. No one is displacing to EWR 777/756/737/320. So you are going to replace retirements and attrition. No one is displacing to the 787 in DCA and they want 75 CAs so they will need a bid. I also pointed out the NB issue......I assume you read what I wrote.

Its not rocket science we still have retirements, and we are getting new airplanes.......

Im sorry you are in a fleet that is currently going backwards but unfortunately you are in a base and aircraft that is going to absorb the loss of the biggest aircraft in the fleet. Doesn't mean the sun isn't shinning, there is just a level 5 over your area.
