does anyone know if the redemptions that are quarterly limited (e.g., Hertz, Hhonors) are rolling or have a schedule? If they have a schedule anyone figured out when they reset?

used Hertz points this weekend to book a 2day rental w/1100 pts. It would have cost $145 for both days, but after applying the points it was only $15 (taxes). That is incredible value for e-rewards $. More than $1 per 1 e-reward "Dollar" (1100 pts costs $120 e-rewards). No other redemption else comes remotely close.
