I have different figures. Srub rate was around 50+% in 80's and 90's. When all thru PC9 started scrub rate went up. Flight screening was introduced with the pass rate fluctuating between 55% and 65%. So definitely an improvement. But stats like photo's do lie. What do I mean? The old planning style of putting double the number you wanted on course to get the number you needed stuck. This simply means if we the RAAF had just put on the better risk people rather than filling the seats by placing high risk people on course the scrub rate would have been far less.
