Yes, excellent point. The actual upgrade time and the time to a CA award have been dramatically different. There's been a huge backlog in training that's kept the actual time slow. In the past, while you may have been on property only 3-4 years when you get a CA award, the guys who are actually flying the line as CA are 6+ year guys. The good news is they're starting to make some progress with training and catch up. Judging by this flow plan, the gap is finally starting to narrow. And later this year we will have a true, actually 2-2.5 year upgrade.
