I suspect AS was lagging on RP to SP and did a batch today to catch up. In the past, I've gotten my 1k SP almost exactly a month after I earned another 3k from surveys. Based on that I expected another 1k on Aug 25 [Correction: I reached the 3k on Aug 25 and so expected the 1k SP on Sep 25], but I just got it today.
Fingers crossed that it will go back to 1 month - or less - in the future.
