Lixma, as you have the best skills to explain all this and also all the information, including the things you just posted about the revi adjustments and the FW190 thing: could you assemble all this into one fluid text/document and provide this to luthier?

Perhaps open a new thread in the FM section with an appropriate title (just an illustration for what I mean - you surely will find a better one than me: "Pilot with two eyes and revi sights: How it should be") and put all the explanations and pictures in it. And send the link to luthier.
