Do you mean what is "auto advance"? Somehow, the unit can change the ignition timing to suit the engine revs (just as the bob weights do in a conventional DK). How it does this I don't know - and I have heard that the advance built into some units is not A7 specific.
I have these units on two of my cars and they perform perfectly. I tried it on another and it would just not run properly - even after changing the coil, distributed top, ignition leads and plugs - so, that one remains on points. Of course, it's wise to carry a complete, conventional distributer with you 'just in case'.
