Several folks on other sites have said that the wait is shorter if you submit at the end of the year or beginning of the year. A friends was 27 days in Feb and mine submitted in March was 43 days. It is stretching out as the year continues, sounds like.

It looks like the wait is going up slightly. I had 3 that should have here thee first or second week of may. One is approved, but haven't seen it yet, anther is still pending. Didn't ask about the 3rd due to some extenuating circumstances. They all were sent in together.
