Fair question BD, and not offended the slightest. All good.

It's not from a book I read what I have stated, it's "manufactured" from the ground up, everything I have learnt in Excel, the this forum and elsewhere, just stating my findings, 30%. ~ Favs.

The thing is, when one "manufactures" their own stats. or whatever, one can go way back right to the very source of their respective data and process.

Hence I added "trivia" in the title bar, yeah it's not a big deal, these fav stats percent are not the only stats. I've collected so far.

There is 2nd, 3rd, 4th and 5th percents on offer to compare, maybe.
