RichardI understand what you are saying.
However, my point is that in a regular erase, one may be trying to remove a pencil or pen mark that has been added after the manufacture of the card (something that was not intended to be there).
In a power erase, the whole image (or size of image) is altered by erasing the original ink for the picture - altering the card from how the card left the manufacturer. I think that this is a distinct difference.
