My original comment still stands. "Would Have" makes grammatical sense. "Would Of" makes no sense whatsoever. Above all, language should make sense, it should convey a thought.

And 6x16 is 96. I did confirm that with a calculator (why not?) but I first computed it in my "grammar head".

This just makes me nuts. Words have meanings, and WRITTEN words should not beg excuses for contemporary speech.

"Would Of" doesn't MEAN anything. It is senseless!
"Would Have" makes perfect sense.

"Of" does not equal "Have", and regardless of how it sounds in contemporary speech, the distinction must be maintained in written English.
