For the CVCX KO Preferred playing strategy, why do the tables not show surrender 8,8 vs 8 at the pivot? According to the KO book, you should surrender Hard 16 vs 8 at the pivot so shouldn't that include a pair of 8s?
What I find to be a bit of a contradiction is CVCX KO Preferred playing strategy does show surrender for 7,7 vs 10 and A at the pivot point. The KO book does state to surrender Hard 14 vs 10 and A at the pivot so I guess that includes a pair of 7s?

I guess what I'm wondering is if you surrender 7,7 vs 10 and A why not surrender 8,8 vs 8? If you surrender in the first scenario why not in the second?
