Pete, I don't want this to come across as condescending but you have a
graph to look for trends and then you focus on a single point of data
that is off the trend line ?!?

Denny, with only 8 data points in about 300 hours of operation time, there
is not much of a trend for this engine yet. I like to think of it as a
baseline, where unfavorable deviations (when something goes wrong) will
stand out noticeably. Honestly, I wasn't expecting this exercise to
produce anything positive.

I am not meaning to come off as condescending either, but have you ever
paid for the cost of a rebuilt or new engine and the installation of this
engine into an aircraft? If so, then you will certainly respect my
attempt at maintaining this engine to the absolute best of my ability.
Given the cost of this endeavor, my desire is to be able to take this
engine well past TBO.

If this attempt includes spotting a favorable deviation in data early (and
I am talking about one obviously lower point out of only eight data points,
not one out of a hundred), then I am certainly willing to explore this
further. Hence the topic in an aircraft owners' newsgroup, where other,
more experienced owners could perhaps substantiate or refute this theory.
