OK, confession time. No, I'm not confused. I'm misinformed by a legitimate published source that should know better. Thank, you, One Room Studios, for the link. By the way of explanation, I am including this (bogus) quote. Not being a techno-geek, before posting any technical comments, I check sources. In this case the "expert" is *dead wrong*. It also explains my real-world experiences with the e609 silver, my first supercardioid, namely the double null. Please note, I am not quoting this to argue with y'all. It's obvious to me that this guy is wrong.
"There are variations on the basic cardioid pattern, including super-cardioid (a wider pattern favoring greater off-axis response) and hyper-cardioid (which has a narrower response yielding almost no off-axis response)..."
