are you sure LSAC sent your updated score report and it was looked at...maybe they made the decision before getting your score.
The dates on all the decision letters would indicate they did. LSAC sent out score report 1/2/08... the earliest decision was 1/18. Seemed like they waited for and went oh just a 166.. lets not even bother to waitlist. The concerning one is UConn even with a 162 I should have gotten in.
I strongly suggest that you contact the schools where you're still pending, and even contact the schools where you've been rejected/waitlisted to make sure they have the update in your file. I read one LSN profile from last cycle (or maybe it was the cycle before) of someone who retook the LSAT and was subsequently rejected by GW. Because of the strength of his score in relation to GW's usual admits, he suspected that they somehow didn't take his second score into consideration. He contacted them and they agreed to reconsider their decision (he was right that it just didn't get into his file for whatever reason). He ended up being accepted.
You might not have such success, but it's worth checking to make sure--could be the difference between accept or reject. And the worst that can happen is that they maintain the rejection you already have!
