I would suggest that if you are already redeeming points at the maximum level - you are probably not overly concerned with the "value" of the points
At least as in value defined as using the lowest number of points possible. Value might be better defined by a comparison to the monetary cost of booking the same room at the same time...and by what not paying monetary price allows you to instead use those funds for.
And, IMO, "storing" large balances of hotel points is never a good idea.
