Geng' the Eng', well, I work with some of those folk and we normally manage to use the correct terminology. Others, however, simply cannot or do not wish to use correct terms. My explanation of SEP, SSEA and SLMG was to clarify matters - hence I took the opportunity to remind everyone that, despite some dozy dinosaurs who still persist in using wrong terminology, there is no such thing as 'Group A' anymore.
I was not a great fan of the Eurocracy of JARs; however, we're stuck with it and people need to use the correct terminology to avoid error.
Just as in engineering.....
