    You are preaching to the choir. I am guilty of using "averaging" as a
    generic term for whatever method the practitioner uses to meld the
    individual observations into one useable point of time and Hs/Ho for
    reduction.  Popular methods seem to be averaging, linear regression, and
    fitting to slope.  I have long been a proponent of fitting to slope as the
    list archives will attest to.
    I do understand it is fall in oz (which seems to be not to your liking), and
    spring in the states. Keep you spirits up by getting at least 15 minutes of
    sunshine a day--sailing season will come around again.
