Sometimes, usually over the weekend, WGT lags in awarding the points. In the east, ncviz pointed out that 7PM was the start time on the CDP clock. This holds true but sometimes, when you play after 7pm you don't get the points until the next calendar day but you get them before 7PM. Once in a while you don't actually see it pop up and other times you get 2 in one day. The consecutive streak stays intact. This is for EST and somebody in the west posted recently that their time was 4PM. It fits.
Think of the days in 24 hour blocks starting at your time. Conceivably, you could play a game just after 7 Monday and have almost 2 days to keep the streak intact-just play before 7 Wednesday.
