I read post 23 and it was not specific, thus my question. It says that the drop to GLD may be brief, leading me to think that it's not seamless, thus you must drop on 3/1 before being upgraded again. The question is whether the brief drop is the time to your first post 3/1 stay or just the time until the next 12-month sweep.

In either case, if it's not seamless, nights from 1/1 to 2/28 in the previous year would be lost. If I have 74 nights in '09 but 30 of those in the 1/1-2/28 time frame, then by the time I drop to GLD and the sweep runs, it's for 3/10/09-3/10/10, so those 30 nights are lost. The sweep only shows 44 nights, plus whatever I have for 1/1-2/28 of 2010.

So the question remains - is there a 12-month rolling check of 75 nights on 1/10/10 because the system knows I would be dropping to GLD, or does it not happen until 3/10/10 after I have actually dropped?
