We didn't run any classes from 6/08 until 9/10. However, that puts nearly 800 FOs that were hired 6/08 and prior that haven't upgraded yet. You can come up with your own assumptions on how many we'll upgrade every month, how many will decide to stay in the right seat, and how many will quit, etc. before we get to a 9/10 DOH upgrade.

Don't forget, about 65% of our attrition is out of the right seat.
