BRC 1955 - The Golden Age [Qualifying R5]

[strop]

thanks for the info Martin. I'll continue retuning as planned then!

You can easily check if you were affected by the bug: take a look at you trim file and search for ["MinDiameter"]. In the lines below there are the two values ["Front"] and ["Rear"]. If rear is above front you are probably faster now than in the last video.

Info for all: mattmr2, RubenSL, strop and Absurdist are not affected. TheBobWiley for example was.

In my save rear is above front. Was it fixed for everyone?

[Der Bayer]

Sure. The program takes care of it, no manual work required.

Nice.

My car should run faster now? surely you speak in maddening riddles....

Pre-Season Test 2.5

Hey guys, I finished the revised Pre-Season Test: http://youtu.be/oD-PGZ8Ok5c

In addition to the mentioned bug I rebalanced the driveability/sportiness dependency to result in (hopefully) a bit more understandable performance.

[Dobble]

Well that didn't work. Slower top speed, slower lap time and the same tire wear. What now?

[strop]

I confess, I came away from that test with less understanding of what's going on. It seems my car is now 3-4 seconds a lap slower on average? Also, I see Killrob got rather more negatively affected. May I ask how the driveability/sportiness dependency was altered?

[Der Bayer]

All times are now 2-3 seconds slower because of slightly reduced cornering speeds. This results from adjusting the penalty for drivability/sportiness (or better: TrackTameness/TrackSportiness).

Before:

  Code:

    TSratio = TrackSportiness/TrackTameness; %Based on this ratio cornering speeds drop if sportiness is higher than tameness.
    TSpenalty = (TSratio/1000)^0.5;
    if TSratio < 1; %More tameness does not mean you can go faster through corners than the car can go in steady state circle.
        TSpenalty = -min(0.01,TSratio/500); !!!
    end

so you actually got a bonus for good drivability (TS slightly below 1, this gave a bonus to many people) and a penalty for TS > 1, there is no smooth transition. This was a mistake I made a few weeks ago and this is not the in the original TestTrack calcuations of Automation

After:

  Code:

    TSratio = TrackSportiness/TrackTameness;
    TSpenalty = (TSratio/300)^0.65 - 0.01;


Maximum cornering speeds are adjusted in the following way: v_corner = v_circle_test(radius) * BankingEffect * (1-TSpenalty * TrackSegmentDifficulty)

So I think lap times are much more constant and don't jump around as crazily as before if you do minor adjustments to the car. I will take a look at the trump cards, but I have the impression that the performance figures on the cards correlate much more with the lap times now.

Thanks for posting that Martin, I see how it works now! I'll see if I can get a retune out tonight...

[RobtheFiend]

Okay, my driver is a human after all. He made ONE error, a whopper of 2.7217. But i think my fastest laptime was a little lower than previous.

Maybe time to retune the car a bit, this is still the first one i sent in.

[Killrob]

Hrrmm, that was a quick decline to mediocrity! Still not changing things though, I proudly race in the mid-field.

[JasonPoland]

Thanks for hearing me out DB

[Absurdist]

Wow. look at all those 1:40's. This is getting really competitive.

I'd be interested to see where the highest placed cars are that are using alternate bodies.

Mattmr2's car is seriously quick. I went all out to hit a top time this time. I couldn't seriously run that car in a race for fear of it imploding.

Regarding tyre wear, no doubt the tyre wear is more pronounced, but I suspect that at this level, the difference between the tyre types is too small to make it worth using the slower tyre.... (Subject to embarrassing correction).

[TheBobWiley]

Lost 9 places.... wellllllllllllll, crap
really don't know what can be changed on my car.... guess its just slow as crap :\
