You can find the long thread by using the search box at the bottom of the main page and searching for "Axis A22 Wedge".
Basically it gets lost in guesses and opinions at first, but eventually some folks get their gopro cameras to watch the wedge in action which resolved the questions to my engineering mind. The deal is that what they (dealers for example) call a floating wedge that can pivot as the boat's deck angle changes is a bunch of hokum. The wedge is hydrodynamically forced down and, therefore, toward the boat transom. The further out it is held, the more downforce it creates. There are two bolt holes. The bottom one holds the wedge further from the transom and that gives the higher downforce and bigger wake. Mine was delivered in this position. Sounds like not all come this way. In my weighting configuration at 9.8 to about 10.5 mph I can produce monster surf wakes that the kids rave about.
Here is a direct link to the page where the pictures and videos clear up the myths.
