C = DCI then MUST park approximately 3 (between 2.7 and 4-ish) 50 seaters

Every time A happens, then the process can begin again until B = 70. Then the hard cap is reached and any further growth can only occur at mainline.

Every 10 times B happens, a snapshot is taken of the Mainline to DCI block hour ratio. That ratio becomes the new minimum ratio and cannot be reduced - ie mainline shrinks, DCI must shrink by the same amount (block hours not airframes.)

What you're suggesting is not possible under the proposed agreement. Hope that helps.
