Its nearer 50 than 2
And that is the problem with Stats - they are just a snapshot in time; a day later and the picture might change dramatically. So (as has been pointed out before but you have ignored) I know of 6 air cdres that have PVRd in the last couple of months; I've also heard of a couple of brigadiers who have done the same. So a snapshot today might not be vastly different but it will change in pretty short order!
Unfortunately, several of those who have PVRd are our brightest and best; which doesn't necessarily bode well for the rest of us and the future!!
I also agree that SDSR should be job for 15/16; with the actual decisions and announcement into 2016. Let's face it SDSR 10 was rushed and certainly not a true Strategic review!
