Just saw the spreadsheet with the color coded setup. It may be just me but I would argue it looks good. Most were within spec or margin of error of the machine. And a few less than steller companies dropped the ball completely. I would make one more change a color for being above the HRC but within margin of error of machine, just like the yellow. And one color well above that, I'm thinking purple for this as only a few knives fall under this that would require a change.
