I hope the upgraded SW will be corrected soon again.

In the past KG was issuing incorrect sharpness certificates saying that 100 on BESS ≈ 1 micron. After some time and several interventions from different sites in the world it was corrected by dividing the apex width by five! The initial error was not a misprint, it was done intentionally. The motivation was to speak the language of the local customers. The current KG certificate is OK.

The great role of constructive feedback, provided e.g. by CBWX, is to keep everyone on track and help to avoid major mistakes, namely in the concept.

So, what is the correct relationship between apex width and sharpness and is there a way to relate that to BESS scores?  If I read your message correctly, it sounds like the apex width of a 100 BESS score would be about 0.2 micron. 

Is there reference material to look at?  Was this posted here and I missed it?

Quality is like buying oats.  If you want nice, clean, fresh oats, you must pay a fair price. However, if you can be satisfied with oats that have already been through the horse, that comes at a lower price.

Yes Rick, you are correct. The apex width of 100 BESS score should be about 0.2 micron (200 nanometers).

A word on home-made FVBs.
4 months ago we started CNC machining the FVB base, and have tolerances tight.
If your self-made FVB does not have the base of the same thickness as ours or legs in the wrong position, you will be getting less accurate results, and all the man-hours we've put into this software improvement will be wasted as you will not be getting better deburring and sharpness with it.
I'll be stopping making custom applets for home-made FVBs because of that, because formulas by themselves will never match the algorithm fine-tuned to our particular FVB make.

Could you post or send me the measurements/print to the FVB so I can fabricate my own in our machine shop?
