At least you could give AndyF credit for that photo...
Yes, AndyF does get credit for the photo, however, the premise of that photo is incorrect. The fulcrum length has nothing to do with proper geometry as it relates to efficient, stable, valvetrain operation. For me, all it means is "How far am I going to have to offset the shaft once I have it at the correct height?".
