I was told that the FAA hours build method mentioned above is not recognised by JAR so would be a complete waste of time.
Of course, people sometimes make things up just to appear knowledgable so my advice would be to pick up a phone and get onto FCL at Gatwick and find out for yourself. There are lot of know it all bull!!!!ters around in the commercial flight training world so it's often best to get off ones arse and get facts straight from the horses mouth because some people will say anything just to save losing face.
VFE.
