SGTLee, I agree with USMC regarding it coming out in batches.
~ Yes, the bulk do come out on one day, but some drip out for a couple of days. Remember that Monday is a Federal holiday, and that may mean the drip might extend until! Tuesday.
Also, before concern occurs, wait to see how much this thread lights up. If it is a few than the spigot is still opening up and many rewarded maybe the perfect match, that without a doubt would be awarded a scholarship to their school choices/intended majors
~ I.E. they placed more safeties and matches than reaches.
~~ Your DS may have placed more reaches and less matches, with no safeties.
Do not read anything into it. The real light up tends to occur between Thanksgiving and Christmas....kind of like college early decisions.
