Well, I recently came back to GPRO and obviously can't remind all things, but one that I couldn't find was this mess with the Practice 1 info. So, you got the laps, driver error and net time. Net time is my main goal, and I already saw that is a "range" of satisfaction for the driver when analyzing the car. My problem is, he is actually decent in Technical Knowledge, however his best lap (+ Net time and fewer errors) was one which he wasn't satisfied with the setup (slightly) - Those he liked had something like, 0.01s more in the net time column. Maybe in a race, 0.01s can make a difference, but does his satisfaction worth more than that?

Do you know the size of that range? I think that's what you are missing. Sounds like you are standing at limit of the range but you are not doing next step, which would be aiming the mid point of that range.
Don't overthink the 0.01s, it's negligible.

http://prntscr.com/n209pg But that is where it sounds weird, I know about that range, but somehow he was faster when out of his comfort zone, I guess... Not sure if the picture has the same meaning of "aiming at the mid point" that you said previously... Probably the statement would be "if you raised it a bit more he would be also faster and happier", am I right?

Not sure if I'm following, Vitor. First of all, are you working the 5 values independently (both wings, engine, brakes, gear, suspension)? Driver can be happy with some of those and unhappy with some others.

No, no, I only made changes in those 3 setups about the wings, that's why I left the 7 there to say they are between 700 and 799 (not sure if posting a full setup here is allowed), but all the rest is the same. (btw, are there moments when different values for FWing and RWing makes you faster?)

Ok, now I think I have a better context.
Driver is satisfied at lap 4 (higher value), he's also satisfied at 8 (a bit lower, but not as low as lap 5) and he is not satisfied at lap 5 (lower value of them all). It seems that the limit of the range is in a value between the one you used for lap 5 and lap 8, but you have not found that exact value yet. That is normal; if you had another practice lap the logic next step would be (value for lap 5 + value for lap 8)/2.

Oh, that's nice to see, will keep an eye on it when making new setups. (Added to that, there's a possibility that my FWing was closer to the ideal spot when lowered and my RWing wasn't, am I right?)
Yeah, I still need to "re-learn" on how to optimize my setups to avoid situations like that, but after all, the main point is 'should I ignore the satisfaction of my driver to get that extra 0,02s?

It's better to use the same value for both wings in order to find the limit of the range. What helps you know how far or close of the limit you are is the driver commentary. Wing splits affect net time, but you shouldn't be testing wing splits until you know the limit of the range and calculate the mid point of the range.

You should never ignore your driver's satisfaction; but wings have the WS factor and that creates a distortion. Use same value for both wings to listen to your driver, and once you know the limits, test the splits.

In a situation where you've already run all 8 of your practice laps, and there's no more way of finding out a better setup, perhaps yes.
But as Florencia said, since your driver is not satisfied, the perfect setup should lie between laps 5 and 8.
Also, I wouldn't try to adjust your standard wing values (for example both wings 550 -> 520) at the same time as checking for wingsplits, so when you check for wingsplit, the average value of the wings should be the same as the wings had in the previous lap, so you can see the exact difference that the split made (otherwise changing the wing setup would influence that lap time)

He never suggested he was doing this, and if you look at the screenshot which shows the start of the second figure on some of the values, it appears as if he was using the same values for both wings. Why wouldn't he given he didn't know that wingsplits were even a thing until this thread.
That doesn't mean that wingsplit effects cannot affect the times though.

Yes, I mentioned it because I wasn't sure Florencia's comment made it clear enough to a new manager who just heard about wingsplits ^^
