Then the annual rates do not vary that much as a whole, with each year being compared with 1999/2000 and being pretty stable really. 2001 was an odd year and last year was down on the normal.

However this is very telling.....
Gains to the Trained Strength of the UK Regulars in the 12 months to 30 September 2006 was 13,860p compared with 15,580 in the 12 months to 30 September 2005.
RAF Gains to Trained Strength fell by 50.2p percent (1,530p compared with 3,070)
RAF Trained Outflow rose 21.8p percent (5,080p compared with 4,170)
