400 pilots at PSA means 200 upgrades.
We have approx 250 f/o's.
So if you come to Psa you will not upgrade in less than 2 years.
Do the math. 10 pilot upgrades per month.
20 months to get the 200 upgraded.
Then 5 every month after. The 250th f/o right now on property has at least 30 months before they upgrade. Then all new hires are after that.
A 3 year upgrade average is most realistic.
