RN FJ training's certainly running a lot quicker than the RAF pipeline at the time being.
RN chaps get "booked" onto a 208/19 course as soon as they've arrived at Linton, and I assume the same thing happens to them re: Linton courses post EFT.
You'll find that the Navy chap on your 208 course will join you from 2-4 courses behind you at Linton, immediately following his grad while you've been holding. Likewise, your 208 Navy mate will go straight to 19 with a couple of weeks off while you go and hold for 6 months, and by the time you're refreshing for your 19/NFTC slot, he'll be eyeing GR7 aircrew manuals.
Go RAF, enjoy holding
