13) Instead of being able to jump at least ten feet high in "one sixth" gravity, the highest jump was about nineteen inches.

No, the highest jump was about six feet.

I think the main reason is becuase the lack of gravity makes it much harder to crouch, and hence build up enough spring-loaded energy (terminology???) to propel yourself very far. Its like trying to walk underwater. Walking and to a greater extent running are both controlled free-fall, which is obviously going to be severely hampered on a planet with low gravity.
