How so?

my figures:
I ran the numbers to assume a 5 hour give for every pilot (not just RSV).
4,000 pilots at jb
2,000 each CA/FO
2,000(5hours) =
10,000 pay hours per seat

I ran the numbers at the top of the pay scale of each seat.
CA 10,000($269) = 2.69m
FO 10,000(($180) = 1.8m
4.49m/month

if it really only affects 20% of the pilot group it only comes out to a $898,000 savings.
