Same composition

To a point where I can predict that it will happen again, and replicate it

That the ability to accurately predict the result has no value?
Exactly.
Too many variables.
You could put those same knives done the way you did it and put them on CATRA and get different results.
Can't make a prediction on something that is bad data to begin with.
The knives have to be exactly the same to start with to compare them.
Same sharpness level that can be and is measured as a starting point that doesn't change.
Same thickness behind the edge, measured thickness, within say .002".
Same edge finish, exactly the same done on the same stones.
Same edge angles that are measured, done on a guided system like the Edge Pro or Wicked Edge.
Have a stopping point that can be measured and doesn't change.
Have testing media that is consistent.
Have set data points that are measured and can be measured as the testing is going on that don't change.
There is a lot more to that just sitting there an cutting cardboard until a blade won't slice paper if you actually want valid results.
That is a massive variable in itself, why didn't the blade slice the paper, could be for number of reasons that don't have anything to do with the HRC hardness of the blade.
And with no set stopping point that can be measured or is measured..... Massive.....
