Partly out of interest but also partly wanting to understand the properties of the knives I have or will purchase I was wondering how much harder an increase of 1 was on the Rockwell (HRC) scale of say 60 to 61.

I'm aware of how this is tested/done and my "research" seems to show that for every increase of 1 the depth of the "dent" caused increases by .002mm so does this equate to an increased hardness of 100% for each increase of 1 on the Rockwell scale or is there an algorithm involved as I'm sure its probably not quite that simple?
