Choice points for future redemptions?
 

I guess we all know that the redemption price for stays varies according to ... well, I don't know what. On the website, they give the current rate and sometimes what it will be a couple of months from now.

I'm looking at redeeming in late Fall, and I'd sure like to know what the rate will be then. When they had a directory, they usually gave rates a year in advance, but now I think they change them every time someone redeems a room. :(

Any clues as to how to find out what it would be in about 8 months? I'm looking at Paris in October.
