No made up values, please. At least I cannot think of any way to guess
sensible average depth based on max depth and duration.

One should also note that the year's average depth is actually the
average of maximum depths (IIRC). Maybe we should change the  title in
the yearly statistics to:
Maximum Depth (m)
 Average         Minimum         Maximum

We have been bitten by the definition of average depth before and that
is why we have disabled it from the Stats tab. But similar change
might be in order to the Stats tab as well. Thoughts/comments?
