I read through it. That is basically what RobMc posted about before. There was one or two statements made that might not be 100% accurate, more marketing than science. At least they admit when using the varying rocker ratio, the faster you open it, the faster it slams on the seat and valve control becomes more difficult.

Their point that a roller tappet has some seat acceleration issue compared to a flat tappet, makes it seem like a good candidate for this technique. The roller already can accelerate in the middle and later parts of the lobe very well.
