<< Gary,
Could you clarify the part of your reply between the astrisks (added by
me)? When you say your trim 'that one section', what do you trim? Do
you remove part of the logged run, or adjust something? Thanks.

On the map adjustments, (was it page 2) you can make adjustments just like
the overall Left / Right and Fore / Aft G's you use on the overall map, but
you can localize these adjustments to just portions of the map based on time.
I don't have GEEZ on this computer, so I am writing this from memory. It has
been a few months since I ran.
For example, you have a left turn on course that should be a tight 180. But
as you entered it, under braking the tail stepped out and you made the turn
with a wide sideways drift. On the map, GEEZ shows this as only a small
amount of turn, and acceleration from 35 mph to 90 mph. You enter the start
and end times of that section, and reduce the accell G's until the corner
exit speed looks about right, and increase the left G's until the corner
curve is about right.
With the car rotated so the tail is facing the outside of the corner, much of
the cornering force was acting on the logitudinal axis instead of the lateral
axis.
The opposite can happen if you push very hard in the corner, so the nose is
technically out. Your speed will show as dropping fast with less of a turn
than expected.
I hope this helps.
Gary M.

Once you have the start and end trimmed, the next one is the end speed.
This
will compensate for a steady increasing speed, which may be a huge
chunk of
your problem. The other thing that will make very high speeds is if you
oversteer alot. Hanging the tail out looks just like acceleration to
the
cube. If you are consistent with your tail wagging, just setting the
end
speed down should get the map close enough to use.
***But if you pushed on some
of the course, but then had a big tail out slide in one corner, then
you need
to trim just that one section. ***
When
I do that in my car, I don't bother totally fixing the map, it is easy
to see
that you didn't really shoot from 50 to 90 mph in the turn where you
know you
had the tail way out. >>
