Hi everyone!

We've put together a new version (6.6) of GPL Replay Analyser for all
of you GPL fans to download.

A couple of improvements and a couple of bug fixes this time.

This is the new stuff:

*You can now print a telemetry page from the graph. The printed paper
will contain a primary graph, a trackmap and three secondary graphs.
Example of a "printed" page:
http://www.racesimcentral.net/

*Added commandline support for automatic generation and export of
reports. See readme-file for details on parameters.

*Fixed these bugs:
-GPLRA could sometimes crash while trying to load a "replay-file" with
no contents (=0 bytes long), this is now fixed.
-Fixed a couple of bugs concerning merged replays. One that
"non-local" laps were merged incorrectly regarding driving line and
the other that some value (roll/pitch) were sometimes incorrect.
-Fixed a bug where the 'lateral' value of AI-cars driving line would
be incorrect on wide tracks.
-The time difference graph in the graph were sometimes acting strange
when comparing laps at very short tracks.
-If you tried to export a report to a txt-file GPLRA sometimes crashed

Download and more info at:

Let us know if you have any problems.

Cheers,

/Martin and Jonas

Ok - somebody refresh my memory. How is the telemetry supposed to help? All
it tells me is that I'm slower everywhere. It doesn't show me WHY...

I don't know how detailed this telemetry is but the telemetry helped me
enormously in F12K2. If you're slow like most people (me included), you're
not slower everywhere, you're probably faster in the exact WRONG place, the
entry of turns. When entering the turn too fast you end up exiting at a
lower speed than a fast driver and thus not reaching top speed on the
straight.

Using telemetry in F12K2 and noticing my poor (i.e., FAST) entry speeds at
Catalunya so I slowed down into the turns and came out faster reaching
higher top speeds in the straights and dropping a full 2 seconds on my lap
times in just one night. I'm not an expert but this basic use of telemetry
is making me a better driver.

Slower everywhere? :) Compare to some non-alien in that case, or
concentrate on where you are slowest and work on that.

Basics on how to use the graph:

Select and load two (or more) laps and go into the graph.

By plotting the laps in the graph you can see differences in for
example speed , RPM, gear used.

If you plot (exactly) 2 laps in the graph you can select the time
difference graph. This is very useful to see where on the track you
are loosing/gaining time compared to the other lap.

If you for example see a spot where you loose a lot of time, have a
look on the different graph and see if you can spot what makes you
loose time. Perhaps you had a higher entry speed and therefore lost
time in the exit? Etc. Not available in GPLRA, but in N2002 you can
also examine where people get on/off the throttle and brake which
often is quite telling. In GPLRA you can use the RPM-graph instead as
an approximation of throttle usage, but different gear ratios makes it
a bit more difficult to compare.

Use the trackmap to make it easier to find where on the track a
certain point in the graph is.

Also compare the driving lines to see if you perhaps take the wrong
line.

I usually start with finding WHERE I am slower. Then I start to look
for WHY I am slower. When you have a certain part of the track to
examine it is a lot easier to understand why than simply knowing that
you are 3 seconds slower per lap.

Problem is that the answer to why sometimes is better car control and
then there isn't much to do but practice or hope for an alien
***... :)

Cheers,

Eldred, find some replays that are closer to your own times. If you
compare your laps with someone who is, say, 3 or 5 seconds faster,
you're probably going to be slower everywhere simply because they're
braking later, carrying more speed through the turns, and getting up
to speed faster. If you look at one that's less than 1 second faster,
chances are there will be a few places where you're faster, and a few
places where they're faster.

Heck, I'm still using the replays that shipped with GPL as my
baseline. I've spent the last 6 months trying to trailbrake more into
1 at Kyalami without washing off the track...

Amazing stuff, as always. Well done. Thanks a bunch! :)

Best regards

Do you have anything that will take my replays and make my driving look
better?? =)

Hey... miracles happen. ;)

I've heard that before - slow in, fast out. But the interesting thing is, I
brake earlier than all the replays I compare to. So I'm *already* slower going
into the turn. The other cars are faster, PLUS they can get back on the gas
sooner. If I brake at the same time, I don't even MAKE the turn. If I get
back on the gas at the same time, I'm off the track at the turn exit.

Perhaps this a racing line issue? Yes, you're slower in but if you take the
wrong line through the turn you're not "straight" soon enough to get back on
the gas. F12K2 telemetry compares racing lines and I was doing this same
thing on 1 turn in Catalunya. I was just as slow as the reference lap into
the turn but my apex was off so my front wheels were still turned preventing
me from accelerating properly. The reference lap driver was already
straight allowing him greater acceleration grip sooner than me and thus, a
higher top speed down the straight.

Sounds like you need to work on yer setups.......

I can't blame the setups. This happens even using the SAME setups.

I noticed something while testing a few months ago. Most drivers unwind the
wheel as they exit the turn. On most of my exits not only am I not unwinding
the wheel, I'm usually cranking more steering input trying to stay on the
track(or out of the wall). Therefore I can't get back on the gas until I'm
sure I'll make the turn, which is usually right AT track out...
