Just an update on my struggles to get the lifetime points accumulatuion. After three attempts spg have manged to track hotel stay point accumulation prior 2003, however it seems to be very hard to track cc card and bonus credits and redemptions as well prior to 2003.
That would explain how they could track life time nights but not life time points (for all members).... We will see if they manage to get to the data points or not. Right now it does not seems like it's going to happen but you never know...
