AddMenuItem4 - how does the Position variable work?

Hi

I'm just finishing up an add-in and I wanted to add a menu entry for the options immediately above Tools > Options. The AddMenuItem4 function requires an integer for the position, and I wondered how this would work. The most obvious explaination, an absolute position, seems daft since if there were several add-ins specifying positions then the newest menu items would end up in the wrong place.

Thanks
