Ah the editor did not let me change the formatting while editing.

This should look better
Otherwise Weigh 2 4 6 8 10 12
It should weigh 42
If it weighs other than 42, refer to weighings "B" below - max 3 more weighings needed
Otherwise Weigh 1 2 11 12
It should weigh 26
If it weighs other than 42, refer to weighings "C" below
