    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.
