BOAC - Is there possibly some confusion in terms here ?
Old Smokey aticulates but the two terms I know are
Mcdr (critical drag rise) - where drag (due shock wave formation) starts to rise at a much higher rate relative to mach number increase ie the total drag curve shoots up.
Mcrit - mach at which 1st local SS airflow occurs
