I think I found the link via HF a while back, but not sure. I use the "W" with 1.5” polyester seatbelt webbing.
Yes, you are correct. Thanks for the additional source info. I finally just copied the pic to my desktop because the thread was hard to find sometimes.

Just to clarify, the "W" method I use is shown in the first two examples rated at 100% and 70%. I think some may be calling this parallel stitching, which is a good name, and less confusing than the middle example rated at 50%.
