I want to jump in here and ask if you happen to have a link or something to point me to a direction of such documentation? And I do mean I want to see them, I'm not trying to be rude, simply curious
It was discussed in another topic recently whether ellipticals cut (front/back) from sphericals provide any added benefit, as their groove wall contact area is virtually the same. Front/back cuts do not seem to add to groove wall contact area. They only reduce the diamond mass.
While some pictures, for example in this thread, may suggest that "vertical" tracing is better with ellipticals, the pictures portray unrealistically dense grooves and seem more like marketing material rather than scientific illustrations.
