So, acknowledging the pointlessness of continuing this discussion, I unsubscribe from this thread. Good evening, gentlemen.
Difference in hardness, even by a factor of 10 means nothing if the softer material is still hard enough not to compress under a joggers foot. There is "anecdotal evidence" for all sorts of ideas that make no sense.
