Actually it's not.

Your flow is only based on the number above you. That's it. Not on the current years it took the pilot leaving now. Same premise as upgrading.

Compass flowed 60% of it's list in the last 1.5 years. The number one pilot who flowed last year was on property for 7 years. The last pilot to flow this year will have been here for 5 years.

Envoy had a couple long stretches of barely hiring anyone, the "16 years to flow" will come down a lot.
