You've rubbished Rod without any evidence whatsoever to back it up.
For every 10 crew that join, how many get into the left seat? If the company decide that 9 of them won't be given a command upgrade, so 1 in 10 gets a command course, passes it, and is upgraded to captain that's not actually a 100% pass rate.
Every other legacy carrier recruited from the same pool of pilots as CX, every other legacy carrier has a better than 95% upgrade rate and, with rare exceptions, everyone does command course.
CX can do whatever they want with their employees careers, it's their train set. You think Rod's numbers are far off the mark? Prove it
