Hi all....
I have some data I can't seem to work out.. During practice, I set up the car and did a lap. Green lap time and 0.3sec of mistakes, but driver was unhappy with settings. Adjusted settings.... Lap time and net times are slower, 1.5 sec mistakes but driver is satisfied... OK...
Re run the lap( in the hope of less mistakes) Same results.... Reverted back to original settings and again, faster with less mistakes
SO!!.. My question is, why is the driver faster with less mistakes with setting they don't like ??
Surely If your happy with the setup, you are more likely to make less mistakes..

How do you FOBY when the data is contradicting...
It's like buying a custom fit pair of trainers but they make you run slower and you keep tripping up......

Not very helpful, eh?
In general: Even if the driver is happy with the setup, it might not be ideal. There's a range of values that the driver considers 'good enough'. And I'd pay more attention to the net time than mistakes when finding the right setup.

in practice you need to look at the net time to get better setting. Me personally usually don't even look much about driver mistake. Rookie drivers probably make also more mistakes than drivers later on in higher groups. You should learn how to setup car at best. Might be good idea to look for a mentor in mentor forum.

First of all, are you checking net time column?
If net time is different with same settings, possibilities are something like car parts or driver skills changed between practice laps.

Sarah, my answer would be - Q time depends on driver's variables /skills/ and not depends on the setup of the car

That answer is misleading Dubravko, can you rephrase it?

Now that is simply bollocks, setup has a huge effect.

I think that would be pretty false statement.
It is important to get best possible setup and driver skills will show how fast he can go with them... also considering risk and car level of course.

So it's a bit of a trade off... eg, he might like more downforce, but that will result in slower in the straights....

The driver is happy in a range, fastest in the middle if that range. And some settings have more impact on pace than others. So a happy driver with everything set near the edge of where he's happy can be slower than he is with some parts set outside of the range, but others set up better.
As others have said, ignore the error times for setup, and try find the middle of the range where the driver is happy for each part to get the fastest setup.

Not exactly... let's just say that if your driver asks you to change the setup, you definitely should. But there are other factors that might change the situation, such as the condition of the car, and the weather.

The net times are very close...0.300 sec between them.

2 laps in exact same conditions with the exact same setup give you exact same net time. So if net time is 300/1000s apart, then you have a reference to keep changing setup values.
As Darryl explained, there is a full RANGE of values where your driver will feel satisfied with the setup, so your objective to get closer to perfect setup is to find the middle of that range.
PM me and I can explain the method to do it in detail.

Simply put, and not what I consider FOBY:
Changing 2 parts settings where one goes further away from it's optimal while the other gets closer to it's optimal can make the time slower despite all parts being within the driver's satisfaction.
Each part's setup is counted separately, not as a whole with the rest.
So with one part near the edge of satisfied result and one spot on optimal and then moving them both will simply set one a bit closer to optimal but the other further away from optimal.

This isn't the thread that I'm thinking of, but it's pretty close to what not-Dr.Perkins would be looking for. There's another one somewhere in the forums from several years ago where Michael Winkley specifically tells people how to get the perfect setup. I don't know why it was never purged as FOBY, but if you look long enough you'll probably find it. Though the info in the post I linked should be enough for anyone to figure it out.

Dumbest post of the year ... and she asked about PRACTICE.
Are you trolling/misleading her on purpose ?
