Question for you Micro while we're at it (if you don't mind) -
Changing CI from 18 to 0 in CRZ results in a slightly higher REC MAX but
can you tell me if the margin is reduced or not? I get the impression it is.
On the Prog page with 18 - 350 350 363 / with 0 - 350 355 369
Looked up the speeds in FCOM and I calculate from 363 to 369 the margin
reduces by 2 knots.
Assuming I'm correct - why would the buffer reduce for the same GW?
