I don't have this book, but it seems to depend on how the
average mammal efficiency was computed. I doubt that anyone
computed the walking efficieny of every mammal.

Now I have to check for which speed CEHE calculated the
efficiency. If it's walking speed, it looks like some people
in this field seem to like remeasuring things ! (perhaps with
an eye toward their favorite views!).
