[color=#ffee00] Updated Weather Forecast - Hints[/color]
Alright, I promised to update the weather forecast because a new weather system was necessary. Here is the new forecast and some hints how to plan your strategy. This info will be added to the first post in this thread, too.
What can be seen in the forecast?
- The forecast shows the estimated severity of rain over the first 90 minutes of the race. Horizontal lines are at 33 an 67% rain, vertical lines are 15 minutes apart.
- It does NOT show track humidity.
- It shows only a “filtered” version of the actual rain. That means the rain will probably be more spikey, can be a bit heavier than depicted and can start a bit earlier or later in the actual race.
- Ignore the three numbers on the very right, these are just input parameters generating the weather forecast for 24 hours.
How can this be used for strategy planning?
- First determine how long the race will roughly be. Some races will be shorter, some longer than 90 minutes. The number of laps per race is in the BRC Booklet.
- Then estimate from the practice results released before qualifying for each race, how many stops you want to make in dry conditions (minimum number of pit stops) and how long you could go on a single tank of fuel and one tyre set before losing to much time.
- Then check the weather forecast for big weather changes. That’s probably when you want to make a pit stop to switch to another tyre profile. Please not that after it stops raining, the track needs some time to become dry again. Watch past BRC races to get a feel for that.
- Determine if you want to use intermediate tyres or not. This mostly depends on how fast weather changes happen and how long rain will stay somewhat constant.
- Check how many stops you would have to make between major weather changes.
- Decide on your number of planned pit stops. Time them a good bit AFTER the major weather change, not before it! That way your tyre profile change thresholds will let your car pit exactly in the right moment when track humidity is bigger or smaller than the thresholds you set in BRCTool.
If you have questions, please ask in this thread.
Enter all of your decisions in BRCTool. Send only the updated *-Info.lua to @Der_Bayer before each qualifying session (if you want to adjust your strategy to the weather, which will give much better race results).
the spikiest is Nordschleife, where you can pit only every 8.5 min. Oh boy 
That should be a pretty good season finale, yes 
Thank you @Der_Bayer for the stats, I’ve sorted it a bit and here is what I got so far:
I’ve excluded Lap 1 as this way was easier and just meant as guide anyways, so it shows total time from lap 2-14. For those that ran out of fuel I’ve set the next lap as an average lap + 30 sec and consecutive laps after that as average lap times

My car has a difficulty of about 1 and the driver made a 97,5% before the first lap got counted AND a 76,6% error on lap 14.
Somebody is getting sacked.
hmmm… why would you and MrChips gain places compared to me? 2 driver errors took 1 sec per lap so that’s 2 sec… And I would still finish behind even if MrChips ran out of fuel… Not sure that make sense.
Still thumbs up for sorted stats
Anyway, a lot of driver errors! [quote=“HowlerAutomotive, post:586, topic:16817”]

Mine has 1.1 and I made 55% and 27%…that’s quite worrying.
This is just a summation of lap times from lap 2 to lap 14, would probably have looked different if all 20 laps were on it. Also degradation of tyres affect lap times differently for different setups
There is still going to be a pre-season test I hope?
Yes, 2 more coming. I just added the information to the first post.
Damn. You are .03 better than mine.
Don’t worry, I’m about to scrap the damn thing.
I need to do something about my tire wear.
Tieing to upload my entry but i cann’t message The_Bayer 
I reverted to earlier development stage, fitted sport tyres and degraded engine durability to 26 . YOLO (Do cool kids still use this days?).
I can’t really improve on my coughcoughferdinandcoughcough RR build. I didn’t yet managed to discover the spell like some folks did .
At some point I considered a garage 56 entry with the goal to race 200 km on one fuel tank and set of tyres. With some testing done I came to the conclusion that the 110 % are possible. The problem are tyres in different conditions. My selection would be sport inters trough all conditions. But how could I get the car to start on inters on dry track 
@Der_Bayer in BRC66 I noticed the pre-calculated fuel volume needed till next pit stop wasn’t ganz genau. And it wasn’t proportional for all the cars.
Well, alot of rain means alot less fuel consumption.
So i would not mind if i had too much fuel for the first stint, due to rain.
But what always bugged me, is that i always got WAY too much fuel in the qualification.
All i want is ~4 laps of fuel for 2 flying fast laps. That would mean about 10kg of fuel for this car.
Even in dry the differences between some cars were biig.
Is there a bug in the BRCTool that it doesnt update the engine costs? I can give mine as much quality as i want and it doesnt change.
Only in the engine tabs though. Trim works as intended. A game and brctool restart as well as re-downloading the brctool didn’t fix it.
I’ve noticed some things don’t update until you go to the trim tab and change something there, have you tried this @FrankNSTein
