What we have seen ...
Last year calls started going out about 3 weeks out, with the stragglers getting called two weeks out. This year has been different (apparently driven by DOJ final background checks). LL has called everybody on Tuesday 4 weeks prior to class every time. I'll be sitting hopefully by the phone this week, but I won't be surprised if they try to reduce this lead time - it is my opinion that they want to be ready to plug the pool drain on a moments notice if the going gets rough.
Everybody needs to keep their heads above water and be ready for a long wait. Most economists/analysts seem to say the good times are coming, but nobody really knows when.
