I confirm that I've got your message, Mike.
Two checks have been agreed as checkpoints for all field testers:
sharpness score after 5 cycles (a checkpoint for “elastic deformation”); and
number of cycles causing "permanent rolling" when measured sharpness does not change any more (a checkpoint for “plastic deformation”).
Steel should be named, hardness if known, and the sharpening method.
There is one more value that we all should record: the Edge Angle
Edge stability clearly depends on the edge angle, and without it the SET numbers will have little meaning.
