Is this a "Call Delta matter?"
No, GUCs/RUCs now expire at the end of the associated Medallion year no matter when you select them (so there is no particular advantage to waiting to do so, although it may simplify accounting to hold off if you have others you haven't finished using up yet)
EDIT: hmm, the wiki needs updating (will try to fix that up now)
