EOU, thank you for your recollection. Appreciated. I share your view that this discussion is important for further deepening of our understanding BESS finer points.
The attached graphs show one possible relationship between the edge apex width and BESS Scores. I do not have enough data to draw a reliable graph, so please take it as one possibility only.
For low BESS Scores the graph is linear, while later its slope rapidly increases towards BESS 2000 for 100 microns (0.004") thick unsharpened DE blank.
