I discussed this with charlest this afternoon and as usual he was able to explain and cleared it up for me. It is very obvious now that charlest explained it. I was getting all caught up in buffer zones, distance from VAL, etc, when actually all Storm is doing is moving the pin further up from the midline with each buffer getting closer to the VAL. Using a 4 x 4 as an example, a 1 1/2 pin buffer will have the pin the highest from the midline thereby creating the most length and flip and the next buffer will be closer to the midline, etc. Thanks again charlest for clearing that up.
