I found out from my UAS Adj because he has a list of all the bursars IOT dates for Oct and Nov. I applied for Oct in the first place.
Not sure whether studes who have done EFT are being penalised more than those who would have to go back and finish it after IOT.
Guess RAF logic would be that those who have finished go straight into holding and why pay us when they can make us wait in civvie world. Whereas those who haven't finished can spend at least 6 months after IOT doing something constructive.
