The point is instead that 12 having more factors than 10 means that base 12 has more easy patterns in the multiplication table (think decimal 2 and 5; in dozenal 2, 3, 4, and 6 are all that easy). 

And when factoring larger numbers base ten has 10^2 and 5^2, but dozenal has 8, 9, 2^4 and of course 10^2.
In dozenal any number ending in 09, 16, 23, 30, 39, 46, 53, 60, 69, 76, 83, 90, 99, A6, B3, will evenly divide by 9
In dozenal any number ending in 14, 28, 40, 54, 68, 80, 94, A8, 00, will evenly divide by 2^4.
In dozenal any number ending in a 2 digit multiple of 8 will evenly divide by 8.

Well, my original post only included the first paragraph quoted; I presume Richard added the remainder himself, but perhaps forgot or didn't know how to move it out of the quote.
