Marius, I think you are right, that the different results on the same blade must be due to different heating origianlly.

Glad to be of help!

Not necessarily due to the ORIGINAL heat treatment but also to the subsequent heat treatments (for example a blade could get bent, and then was heated up locally to be straightened; or a blade could have been dropped into a fire... throughout its multi-centenary history).

And please let me know if you find a source of Nital in Europe as I normally get mine from the US.
