That's just a mathematical average - never managed .69 of a sector - hope I never do
I can assure you that the aircraft regularly do to 2 lots of 4 sectors. Domestics may be 6 sectors in one FDP.
My point is that the LoCo fleet engines do a lot more start/stop/take-off/Rev cycles than long haul. With the global fleet of LoCo A320/B737's perhaps 5 or 6 times that of the 787, the statistics start to look "interesting".
Of course we're not comparing like with like. It can be spun however you like such is the way with stats.
