2001 P 25c Rockwell Planchet Hardness Test Error Suspect

The Rockwell Hardness test would be interesting to find but the indent on the OP's coin is much too large.
(Thanks for the link John1. Every time I read that article I get to remember how much I forgot!!)
In the article, the author Pete Apple, said

This statement made me wonder if the surface of the coin (where the test mark was widest from the testing tool) would be reduced in size more than the lower part of the indent.
Please see the diagram I made to illustrate my question.

Here's my question, after being struck by the die, would the top of the indent be smaller in relation to the lower part?

I hope someone here is able to add some insight. Thanks in advance. PP55

Mike, you and coop are scary smart. The expertise you bring to the Coin World is exemplary. I wanted to post this coin mostly to bring out an intelligent discussion, evidenced by your comments and the one prior from petespockets55. I think that is what a forum should be about. So again - great appreciation to you and those who so thoughtfully post.

The hardness test could conceivably generate a pressure ridge around the pit, but this would be flattened by the strike. As to your second question, the farther away an indentation is from the coin's center, the more likely it is to be stretched out along the radial line it falls on (in this case a line leaning slightly to the right of the N-S axis). That said, I don't think there would be any differential stretching in a pit this small, with side farther away from the center being more stretched out. Again, the pit lies along a column, so any tendency toward stretching toward 12:15 (or thereabouts) would be counteracted by the metal flowing into the die's recesses and into the edges of the pit. Deformation would also be limited due to the fact that the coin was struck in-collar. Not much radial expansion in that circumstance. Sorry for the complicated explanation.

Thank you Mike...
