            GP Race Analyser v4.1 for Grand Prix/World Circuit
            ==================================================

What is GP Analyser?
--------------------
GP analyser is a program to analyse the log files produced by two programs; 
GPLAPTIM, and GPPERF written by Trevor Kellaway.  

GPLAPTIM writes entries to a .LOG file when a car crosses the start/finish 
line, and so enables you to compare your races with the Computer Cars 
(CCs), or other drivers.

GPPERF writes telemetry data for your car as you drive around the track, 
this enables you to compare your 'Hot Laps' with either your own attempts 
or those of other drivers to establish where you are losing/gaining time.

Thanks must go to:
------------------
Trevor Kellaway (or 'Clever Trevor' <g>) for delving into F1GP, and 
writing such excellent add-ons (and letting me get previews of them too), 
and also for putting up with my EM's pestering him with silly questions.

Georg Naujoks who kindly tested the first Beta version of GPA for me.

Greg Foster who helped name the corners on some of the tracks for me, and 
was involved Beta testing of some versions.

Tilman Hecker who kindly spent the time to describe, in thorough detail, 
the smoothing algorithm used in some of the graphs in GPA since v3.20 Beta.

Anybody else who has provided feedback - sorry if I haven't included your 
specific idea, but hopefully, you will still enjoy using GPA.


How do you run GP Analyser?
---------------------------
There are two EXE files in the GPA package, GPA.EXE and GSW.EXE - you only 
need to run GPA.EXE using whichever method you feel most confortable with, 
e.g. Program Manager, File Manager, etc. or you can use on of the other 
utilities available, such as PERF-F1.

Hopefully, all the menu options and everything will be pretty obvious, and 
the toolbar has tooltips, so I won't go into a lot of detail here.  If you 
have any problems, then e-mail me, or post a message on the SportSims forum 
on CompuServe - I generally log in pretty regularly.

NB.  Most of the options when using the Lap Performance window are accessed 
by clicking on the data area of the graph, or clicking on the track map 
(you can click and drag on the map to zoom in).  You can tell where you 
will be able to click on the graph, since the mouse pointer will turn 
into a pointing finger.

Stuff that might not be obvious:
--------------------------------
This program will no longer remove any duplicate entries when filtering a 
race file.

If your log file contains details for more than one race, then it is the 
latter race that is picked up - if the two races are at different 
circuits, then I don't know what will happen <g> ;-)  The best bet is to 
use the extract feature to create a log file with only one race in it.

When analysing GPperf files, laps will be rejected if they; 
a) have too many segments missing (>25), e.g. you jumped a chicane, 
b) have repeated segments, e.g. you re-ran a section of a lap by saving 
   and re-loading, 
c) you spent any time in the pit lane.  So in short, it must be a valid 
   flying lap.  On some slower machines, or if you are using a lower frame 
   rate, it is possible that not all the telemetry data will get written, 
   and consequently you will end up with .PRF files that have segments 
   missing - GPA will reject these files since they cannot be compared 
   properly.

If you run GPperf with the manual logging option turned on, then if you use 
GPA's filter facility to filter all laps from that file, the filtered file 
will contain only valid laps, and no warmup/slowdown laps.

Holding the scroll button down when viewing the track map removes the need 
to keep clicking it.

Problems with Monaco
--------------------
There is a known problem with the layout of the Monaco track.  This is due 
to the way that the F1GP/WC game stores the track co-ordinates, and 
consequently, the way that GPperf reads them.  This does not have any 
effect on the operation of GPA in any way, and is no cause for concern - 
so please don't send me or Trevor mail about it.


Things that are new in this release:
------------------------------------

- Bug in Sort Laps in PickLap fixed (Sort Lap listbox was not being cleared 
  properly)
- GPA will now allow up to 25 missing segments in a PRF lap, hopefully this 
  is enough for people with machines that can't quite keep up with the high 
  output rate.
- Bug when reading .LOG files fixed when sometimes getting erroneous lap 
  details.
- Ability to display Lap Times in Race Comparison
- Bug fixed in Race Comparison when taking an average lap times when cars 
  are in the pits
- Slow-Motion function added to car plot on track
- Focus Rectangle bug in Win95 fixed.
- Cursor Changes to a magnifying glass for the Track map
- Average Throttle position and % Full Throttle added to the Lap Info
- Steering Graph is now smoothed to avoid such jaggy graphs
- Code to stop multiple instances of GPA included
