Looking at the June awards maxtrix (recently posted) I continue to be confused.

If there is a shortage of captains, I would reason that reserve would be virtually non-existent because all captains would be utilized for the available flying, but most bases appear to have about a two year timeframe between SCR and R1.

Why, given the shortage, do new captains have to sit reserve for so long? It seems to me that any reserve time indicates the company is flush with captains willing and capable of flying. What am I missing here?
