Let me remind you of what we are doing here. We are collecting
scientific data to be used for use in future studies. . In fact I
think that is what is posted for what G.O.S.A.'s purpose. Setting my
watch to the atomic clock now seems rather arbitrary if we now allow
things to be noted that could be up to 5 minutes off. Now if in the
future someone is doing a study with some method none of us have
thought of (yes people do think outside the box) that requires some
sort of precise time and the data is incorrect in the logbook they
are using (yes people do log things in logbooks incorrectly) then it
could cause a problem.
Secondly, we do not know what if any effects it has made on studies
but I would rather be closer to correct than not. I have a B.S. in
Geology (emphasis in hydrogeology) and I also have a B.A. in
History and started on a masters in hydrogeology. I can not tell you
how many times logged discussions like this came up in my studies
most of the time I threw out all of that data because it was not
correct data. Also, in my geology studies, I found that many times
when data like off a web cam was recorded it was incorrect. People
who did have a structure in place to note that they were electronic
times did not post them correctly. This in turn made my data
incorrect which I can tell you annoyed me to no extent as I had
sometimes waisted up to 16 hours worth of work. Now, as much as too
little data can be annoying to much data can ALSO be a problem. When
you know you have 5 data points on one item for the same thing you
are investigating you need to take an educated guess on which is
correct.
And about the on-site observer vs. the web cam I would take the
observer any day since I already know that the data from the web cam
is incorrect. If you knew something was wrong why would you continue
to do something?
The guessing often causes more problems than not having a data point
for that one instance. Anyway, I am gonna take the one hour drive
down to Old Faithful from Canyon and go watch geysers.
