If very minimal AB is correct, then it's possible that full realization of P&W's proposed engine upgrades will formally push the A model into the supercruise category.

P&W is talking about up to 10% improvement in thrust in blk 1, up to 15% in blk 2.

If, and I stress, IF they pull it off...

If blk 0 @ 100% mil = 28,000lbf, and @ 100% AB = 28,000lbf + 15,000lbf, then:

(10% imp) Blk 1 @ 100% mil = 30,800lbf = Blk 0 @ 18.6% AB

(15% imp) Blk 2 @ 100% mil = 32,200lbf = Blk 0 @ 28% AB

In fact, the low end of the blk 1 predication is a 7% improvement in thrust, which is...

(7%) Blk 1 @ 100% mil = 29,960lbf = Blk 0 @ 13% AB.

Whether the above is installed or uninstalled thrust should be immaterial given the uniformity in context.
