So....2 that are "pretty" good. Not really good, not great, just pretty good which implies that they aren't as good as they could or should be.
I do not think a 6 foot nile is dangerous to someone who knows monitors.
Of course, we may have slightly differing opinions on what dangerous actually means.
You seem pretty set on what you've learned is not only the only way but anyone else is just wrong.
Have fun with that.
