For the last time, I am not arguing with you that Chuck Billy does not have a good vocal range (or about anything else). All I did was caution you against posting information from The Range Place because most of it is unverified and the site has a lot of errors on it.
I posted my assessment of the data provided because it really isn't hard to believe that he has a vocal range that's just under 3.5 octaves since that's not even uncommon. I'm literally saying that your statement could easily be true.
