Thanks for all the replies, I've read them all with great interest. 
As I posted earlier, the bit rises in the mouth until it uses the teeth as a fulcrum. There is a secondary effect to this which is a lot of "take up" before this comes into play. I do wonder whether some peoples supposed success with the gag has more to do with their inability to maintain a light and even contact in any bit with a more immediate action,eg a snaffle.
