Thanks for the drawing it helps to see pictures. How many degrees of Anti-dive is excessive? I have the Suspension Analyzer 2.0 software. I'm going to start playing with the layout in the picture.
It really depends on your CG height, spring rate, etc. Most suspensions I've set up use anywhere from 2 degrees to about 8, with most being around 6. Too much anti-dive will make the ride harsher than it needs to be, so it's helpful to get it close to optimum.
