Absolutely incorrect. The only way that relative knows no years is if you merge two groups that are exactly identical in age and that is of course absolutely impossible.
If 1000 pilots are placed in front of me on a list and they average 10 years younger than the pilots that were there before, please tell me what that does each and every year they don't retire at the same rate that the others would have.
I'm really tired of arguing about the SLI, so I hesitate to even respond, but there was something proposed by our side to address that concern. It's called a dynamic seniority list. It ensures that you always hold on to your own carrier's attrition, while not destroying any bidding power on the front end. Your NC refused to even listen to the proposal.
