Whilst time to FO on a widebody will never be quick, I'm not sure looking at those recently promoted and comparing time frames is entirely useful.
16+ years encompassing a period of no recruitment for nearly 8 years wouldn't have helped.
It will be interesting to see time to promotion time frames in 5 years when the suggested attrition rates are expected to begin to bite....
