That person is a piker- you'd get between 10-12 different opinions
LOL! Very true (Well, it looks like x, but, wait, there might be some y in there so maybe it’s Z?)
I recall in geology class the tests were to pass around a rock sample and had to say all the minerals in it, percentages, etc. and then name the rock. So maybe 6 or 7 line items, but if you got anyone of them wrong the entire answer (rock) was wrong. And probably 25 rocks per test in fifty minutes.
I recall one where most of us figured on something like 10 to 15% quartz or something. Most of us got it wrong. The professor says “Yeah it looks like 10%, but under thin section (which we didn’t have) it is really about 9 percent - so that’s why you got it all wrong.”
I’m guessing there was some lesson in that.
