I have seen this problem from time to time at one particular
local site. The entire lot has a slight pitch to one side.
I was engaging the auto-start (using notebook to capture)
in grid, which was parked with the nose of the car higher
than the rear. Apparently, GEEZ picks the point at where
the auto-start was engaged as it's reference for "level"
for that recording session.
Leaving grid, there's a 90 degree turn to the left for the
start line, and that puts the passenger's side higher but
the front/rear level. At the end of last year, I was
pulling into the start line, getting out, running around
the car, and engaging auto-start at this point. That took
care of the crazy finish speeds, and even gave a great map
of the first half of the course because the lot's pitch and
GEEZ's idea of "level" were the same. Unfortunately, the
courses there always come back up the lot from that point,
which gets mega-distorted when GEEZ's fudged concept of
"level" gets doubly-distorted with the pitch of the lot
now going the opposite way.
I see the virginia.edu address, and assume that you are
having problems at Petersburg. If so, that lot has the
same basic pitch. Try picking a spot that's a closer
approximation of "level." I've also found that engaging
auto-start in the same place each time at least gives
maps that are all screwed up the same.
Of course, I'll include my disclaimer that I have no
clue how GEEZ works under the covers, and this is just
what I've noticed from using it. YMMV.....
