You ain't no Einstein
Hey Arfur, are you thick or something? No where did he mention any connection to retirements. This is simply about the training department's ability to train captains.
They have admitted in writing a total of 49 successful commands in 2011, which, as 711 points out, is a good year. Ok, it's not their absolute best year ever, but there is an upper limit on training capacity.
For example, doubling last year's total to 98 would bring it down to about 16 years, still not a quick command. However, 98 is not physically possible.
Unless of course more people volunteer for training......
They are still calling for more training volunteers. If they want you to do 30% more work, maybe they should pay 30% extra, rather than 10%.
