Dude,
Did you write an LSAT addedndum explaining your score discrepancy? In any event, the website says that they use the avg (161 for you) for reporting purposes, which is all they care about b/c that's what helps the ranking. If you were a clean 166 they would have taken you easily, no problem. Don't you wish you had cancelled that first score ? I got the same kind of thing going on, and it makes me curse the heavens every day for not cancelling that first one when I knew I should....
