I dunno about that. MH (LAX/FAT CP, everyone's favorite pilot) spent what, four months as a CA before being named ACP?

Also for CP/ACP it helps to have:

• No sense of empathy or compassion

• A stick jammed extremely far up your six

• A nice shiny hat, plus the gall to call out other pilots for not wearing the (not required) hat

• A startling lack of actual airmanship (speed limits below 10,000 feet? If you're a CP, they don't exist. 300 KIAS is just fine. Oh, and when your FO gently reminds you that you're about to inadvertently take off unpressurized because you shut down the APU on a 100-degree day in PHX in a fully-loaded CRJ-200 just to save the company money, but forgot to swap the bleeds to the engines...be sure to blame the ground controller for talking too much and distracting you. Do this, and you're perfect ACP/CP material.)

• The ability to use the phrase "for the good of the company" 100 times a day, and still be able to look at yourself in the mirror

There are certainly exceptions (RG being one of them), but do a trip with such wonderful human beings as MH and you will see what I mean...
