Frank,

Yes, you are right, and maybe I am not remembering accurately from so long
ago.  But I do remember we were all amazed by the results.  However, the
samples were few, and could have been just lucky estimates.  But bear in
mind that the observation does not have to be just one estimate.  For
example, record when the squash is first detected.  Then record estimates as
the squash continues until sunset on whatever the horizon is.  Having prior
knowledge of time duration of squash, maximum amount of squash, and shape of
the curve in general, and you can get a pretty good estimate of the event.

Ken
