Success! Closed on 4/7, Deed recorded in Orange County on 4/8, points showed up the afternoon of 4/21 (and weren't there this morning). So, a 13 day gap.
Of note, I have yet to get the official letter, but was luckily enough to encounter helpful CMs on the phone lines that helped me with all the numbers I needed to get the DVCmember account up and running.
