I didn't say "incomprehensible"..and as for inaccurate ..either you already know..in which case I'll not rise to the bait ..I have better uses for my time..and if you don't know..then sorry :) but I gave up teaching for free in public over 30 years ago ..

Nowadays I not only charge highly for teaching and all other work ..but I also refuse clients..:)
