Everyone across branches and fields who received a March update got the 3/18 update, indicating its significance. The 3/13 and 3/19 updates remain unclear, with only one person receiving 3/13 and two receiving 3/19. Notably, no one in fields including Chemistry or CS across branches has received a March update yet, which is unexpected. Last year, all March updates happened on four specific days, with decisions following the day after the fourth update. So far this year, three March updates have occurred. I previously suspected that each update corresponds to an action by a military research branch, followed by a fourth consensus action (3 + 1), but now I am unsure. More March updates is not necessarily better; last year, the person who received three updates was waitlisted. However, receiving at least one March update seems necessary. Last year, everyone selected or waitlisted received at least two March updates, always including the final one on 3/21. Based on this pattern, I expect one more March update opportunity before final decisions.
