I received an August launch permit in the mail today. One of my friends has a permit for the same section the following day! We will put our heads together and give up one of the permits. Another friend has a permit for the other section, but unfortunately the dates do not line up. We should probably coordinate a little more closely next year.
I have never seen any statistics, but my understanding is that permits on the San Juan are pretty easy to get, except for May and June.
