Absolutely not. At least one school thread is reporting more TODAY. As we have been saying all along, the first big wave will go from the end of April to the middle of May. That's now over. What we will have from here to the end is a series of smaller waves, each one a little smaller than the one before.
The reason each one is smaller than the one before is because, as always, movement is caused by excess As being dropped. The biggest surge is right after 4/30, because that's when the most As are dropped at one time, due to the requirement to drop to one by 4/30. Many people ignore the requirement to drop to 3 by 4/15 since it cannot be enforced.
Starting on 5/1 multiple As can only be created by people already holding an A being called off a WL (and, of course, people with extensions milking them to the bitter end). Every person receiving an A who didn't have one before is a very happy camper ecstatically reporting success on SDN represents one less call in the next round. Calls will continue into June and July, but there will be fewer and fewer of them until all seats are finally filled.
The big question -- has most of the movement already taken place, or will the movement over the next six weeks or so equal or exceed that of the last two? I honestly have no way of knowing, but reported WL movement from prior cycles suggests that it is far from over. Really, after studying this for the past two cycles, if it were me (and, it very well might be next year), I'd be cautiously optimistic through the end of May (depending on how many WLs I was on, and whether school gave me any indication as to my position), after which I'd start focusing more on gap year plans and less on attending med school in two months.
As you know, things can and do change right up until the end, but, just like it's premature to throw in the towel on 5/2 (as many people who received As in the last two weeks wanted to do, right here!), it's also overly optimistic to be counting on a miracle the third week of June. Praying yes, counting no.
