Saving Gammon

"The Last Act of a Desperate Man: 4 Exercises in Getting Off the Gammon."
Problem 1

Black now has 28 saving rolls and 8 nonsaving rolls. The move 3. 14/8 gives only 26 saving rolls. 

Black now has only 3 bad rolls (21 and 44). This is better than 3. 15/6 which gives 4 bad rolls (54, 55, and 44). 

Black now only has 5 bad rolls. All other possibilities produced more bad rolls. For example, moving the outside man all the way (10/7) gives 7 bad rolls. Also, moving 10/8 and then slotting the 5 point gives 10 bad rolls (slotting the 3 point is even worse, producing 11 bad rolls). 

This is the only way to give Black 5 saving rolls (double 2's, 3's, 4's, and 6's). Some possibilities, such as 15/9 or 15/10, 8/7, give only 3 saving rolls.
