As this discussion has shown, if you set field elevation
before takeoff and don't change it, then finish with
500 feet on your altimeter, Windscore won't flag you
with a penalty. That's what I do and I haven't been
tagged with a finish penalty yet. Start gate is another
story......................

I don't find this to be true, Andy. Altimeters need
to be re-set primarily when landing at a destination
1000's of miles away from the takeoff location. I
find
my altimeter to be surprisingly accurate when landing
at my takeoff location after a 4 hour flight. This
is true with the SN10 altineter, also.

JJ,

My observation is based on analysis of many of my own
flight logs. I
am so convinced this 100 foot difference is valid that,
if there is no
local altimeter setting available, I set my altimeter
100ft lower
before starting final glide. I had planned to spend
this evening
reviewing your recent flight logs but I don't find
you as a registered
OLC contestant. Perhaps you could check a few of
your logs,
measuring the exact difference between on ground altitude
at takeoff
and on ground altitude after landing and report the
results. If you
use Parowan logs please allow for the difference due
to runway slope.
( most days I was there this year takeoffs were from
the low end and
landings ended at the high end)
