"Vince Klortho's diggings from ISI are terrific:

Ok here's the current situation with RCD files:
Aggression 0 - 100 (%)
As this number increases the AI will give other cars less room, both while passing and while following.
It also increases the frequency at which they try to pass and the increases the threshold they are willing to endure before giving up a pass (or crashing, as the case may be...)
The aggression slider in the UI also affects this directly. RCD Aggression * UI Aggression = final....and should always be between 0-100%.
Reputation:
Recovery:
All but worthless or no longer used.
Composure:
The lower the number, the higher the frequency of "intentional" mistakes. (if AI Mistakes is > 0 in the playerfile)
If AI Mistakes in the playerfile is set to 0.0, then the AI drivers never make mistakes. *cough* Well, mistakes that I planned. "intentional" mistakes are things like, taking a turn too wide, or missing a breaking point.
Increasing composure also decreases the time between bad driving zones. (also affected by the playerfile variable AI Limiter, see MinRacingSkill below)
Speed: 0-100
How close to "optimal" this driver drives a track.
This number directly interacts with a variable in the AIW file called "AIRange" AIRange tells us how wide the gap, from 0-100% (expressed as 0.0 to 1.0 in the AIW).
The default is 0.1 meaning that the full range of Speed RCD values from 0 to 100, are directly mapped to the top 10% of the max speed = 90-100%.
For example a driver with 100% speed will drive at (0.9 + 0.1 * 100%) = (0.9 + 0.1 * 1.0) = 100% of what he thinks the track can handle, while a driver with speed = 0 will drive at (0.9 + 0.1 * 0%) = (0.9 + 0.1 * 0) = 90% what he thinks the track can handle.
There is a random fluctuation in this value, but it's much less than in previous version where the random fluctuation was so great that it made the original value meaningless.
Crash: 0 - 100 %
CompletedLaps: 0 - 100%
Only used in auto completing laps (skipping practice/qualifying)
MinRacingSkill=0 - 100%
When the AI Limiter variable(from the playerfile) value is > 0.0, the AI drivers go through cycles of optimal driving and sub-optimal driving where their driving skill falls to MinRacingSkill * Speed.
(Set the AI Limiter variable to 0.0, and the AIs will always drive to the best of their ability...every lap)
So for example if you have a driver with Speed = 50, a AIRange in the AIWfile = 0.2), and MinRacingSkill = 90.
This AI guy will usually drive around at (0.8 + 0.2 * 0.5) = 90% speed (really very very slow....but this is just an example), but will sometimes dip as low as (this speed * MinRacingSkill = (0.9* 0.9) = 81% while having a bad lap.....that is extremely low, but this is just an example with easy numbers.

You should also consider training the AI, takes a few minutes per track but improves their line.

rFactor AI Calibration
Should you find yourself having a little trouble with the AI being poor in your favourite mod on one of my or anyone else’s tracks then you should follow this calibration tutorial to improve their performance. The following tutorial is a repost from this RSC thread by Rob Cook so that I can post a link in readmes for releases.
1. Make sure you do NOT have rFactor running in the background when doing the following or else the modified file will revert back to the non modified state.
Go into your player file at C:\Program Files\rFactor\UserData\[player name]\[player name].plr.
Go to the line Autocalibrate AI Mode=0 and modify to read Autocalibrate AI Mode=1.
Now click exit and SAVE the player file.
2.Start rfactor and choose Any mod, then SETTINGS and change the following SETTINGS: – In the RULES section:
Flagrules,Fuel useage and Tire Wear to either NONE or OFF. Private Testing ON
Now on the right side of the rules screen change to the following settings:
AIDrivers=1
RACE GRID Position=1
RACE START TIME=8:00 am
RACE TIME SCALE=NONE
Mech. Failures=off
TYPE OF START=STANDING
3.Choose the car you want under VEHICLE to teach AI to run this car type properly on any track.
Then, go to TESTING and choose the track to learn and LOAD CIRCUIT (bottom right), but DO NOT click on RACE.
Make sure u are in the MONITOR mode screen, and click on ADD AI.
AI will now start its training and tells you to STAY OUT OF MY WAY HUMAN, do not go on the track to drive your own car, just watch the AI.
Press the VIEWING button to view the AI on the track.
Now press the R button on the keyboard to be shure the driving window will show ‘LIVE’ in the upper edge of the viewing screen.
HighLight the AI on the track, by LEFT clicking on the AI’s name in the MONITOR field, you will now see his best times change, as he progresses. After watching him for at least two laps LIVE, press (Ctrl) (T), this will speedup the time it takes to run a lap, but will NOT effect the accuracy of the Learning Mode. It will just make the AI finish his learning mode faster than normal.
Now we assume that the AI has finished his learning mode and told you he has xxx.xx meters left over, if at this point the meters left over does not show 0.0x, do the following:
Make sure the AI’s name is highlighted in orange colour, then click on BOOT. (You are deleting this AI from the Learning mode).
Click on ADD AI. You will now see a new AI name (if you have more then one AI) and he will now continue the learning mode where the last AI left off. This second AI will get the amount of meters leftover to 0.0X, and when he finishes the INI file created will be updated/overwritten.
Speaking of the INI file, the following is the manipulation needed for all the cars to use it not just the team that did the AI LEARNING.
Look in C:\Program Files\rFactor\GameData\Vehicles\[car]\[team] now in the TEAM that did the learning there will be a .INI file, THIS is the file that needs to be moved so that all cars in the chosen mod can use the updated learning file. What you do is CUT the file and paste it in the CAR directory of the effected car. So SAVE it to C:\Program Files\rFactor\GameData\Vehicles\[car]. The dir that has the .HDV and .TBC and other car related files in it.
4.NEXT STEP I THINK IS VERY IMPORTANT!!!
Go into your C:\Program Files\rFactor\UserData\[playername]\[playername].plr file and reset the line ‘Autocalibrate AI Mode=1 and modify to read Autocalibrate AI Mode=0 again.
Also go back into SETTINGS and reset all RULES as you previously had them.
This should in theory improve the AI performance on the track you ran it on. As an AIW creator it is pretty much impossible to make an AIW that works for every mod due to the huge differences in quality of the mods and how they react to the curbs etc. Running this may take a little bit of time however if you race offline a lot it will most likely help you a lot."
