you said YEARS per century, so you’re TECHNICALLY right.
But you’re wrong because you were arguing against my statement of 7 TETRADS. So you must have meant 10-12 tetrads but since at that point you assumed a tetrad lasted 1 year you simply used the more common term year instead of the unfamiliar tetrad. For there is no good reason to switch the subject from tetrads to years which are not identical, UNLESS YOU THOUGHT THEY WERE!
Then as you found yourself squirming under the vise of my gigantic intellect you came up with the 10-12 year defense. Good try! If not for my lightning fast grasp of your well disguised attempt at logical subterfuge you might have succeeded.
As I’ve said before, it will be a cold day in December before YOU can outsmart ME.
