One of the reasons that BAOR Cold War warriors became disaffected was that the Treasury did the double whammy of reducing the FFR (12 DMs to the pound when I was a padbrat - and 4 DMs and falling when I was serving) whilst simultaneously REDUCING the LOA. The attempts to explain this phenomena simply defied rational explanation - as indeed does the whole basis of the FFR itself. One would think that in the most advanced and successful economy in Europe that things would be getting more expensive not cheaper. I wish you luck.
Strange one how it has suddenly changed now when the Euro has been in decline for quite some time.
A quick example is Pte Bloggs paid 150 euros (£100) for flight home for Xmas and returns to Germany on 02 Jan 08. He claims GYH(O) and chooses to have it paid into his German account voile he gets back 140 euros due to the change in FFR.
Could be the cynic in me but it was also strange that the rate your allowed to claim for a flight went from £120 to £101 during Summer Leave last year?
