Plotting the number of medals issued to their geographical locations is a commendable exercise David. I know you are showing the Western Cape in your example, but please expand your reach to include all e.g. Natal, OFS etc.
I'm not sure that this will help with the naming style IL. What were your thoughts around that?
Here, I don't see too many TG QSAs (I only have 2xKTGs plus a "Talana" to Dundee RA) and I have sometimes thought that TG QSAs might exhibit naming variations; thin caps, square caps or engraved. Indeed, there might not be any naming style variations at all. I just don't know.
