You did say FYI, there was no way to know it was a plural your i.e.
"beginners this is FYI".

It might also be argued that despite the fact that the group caters
for beginners (as well as experts as it happens) there should be no
pressure for any contributer to try and act as a role model in
everything they do. The video was to display speed not efficiency and
I don't remmember it being touted as an optimum or advanced design
just a fast and cheap one.

Optimization of tool paths is a really interesting topic and it was
worthwhile noting that the tool path was not optimal but I can see why
conflict might have arisen even if no offence was intended as I am
sure it wasn't.
