No Problem. Thanks very much for your very detailed reply,
which obviously took considerable time to write. While
I was making progress, your instructions really fill in
some gaps and mistakes I was making.

Eventually (probably several days) I'll report back my test
results.

Due to incompetence on my part, the config file being run for my tests was
always just the default config file from my original
git clone https://github.com/gormanm/mmtests.git
command. So regardless of what I thought I was doing, I was running "pft"
(Page Fault Test).
