LFS (and Airio) uses hundreds of nodes on each track to determine where a driver is, and thus work out whether someone is going the wrong way or not. Since AS1X does not have a path or nodes to define the track, LFS cannot work out which way someone is going. Luckily EQ Worry is creating custom ones for Airio, so a lot of the problems (cutting, blue flags, wrong way, and hopefully yellow flags) should be solved in a new version of Airio.
Phil, do keep up son. A16 is the short Aston one, basically A12 minus AS1. A17 is Touring Car Short, A14 but without the AS7 hairpin, like you say. But if you want to go ahead and do A18 that's fine by me - it's not the best track but meh.
Incidentally, the OP has been updated with a newer zip file
We've had people saying he's been dead for years, but never had any hard evidence about it - neither have we seen any in this case (apart from Saint Barack's words) so I'll wait and see what they produce as evidence...
It's different to LFS' systems which use yellow flags. You get incident points which you collect in official sessions - 1x for off-track, 2x for loss of control, 4x for car contact - which are used to determine a corners per incident number over your last 2600 corners IIRC. Each licence level has a CPI number (rookie will be more lenient than Class A) and your SR will go up/down according to where you are in relation to that. As you can see, sure, your SR may go down a little bit (biggest drop I've had was about 0.30 or something for 20+ inc in a race) but if you keep driving safely you can gain back lost SR easily.
The above quote supports the following, and disproves your own point!
iRacing: lose position + lose SR
real life: lose position + lose money repairing car
You mention that you "only" got +0.1 - you need to read more about the SR system, and you'd know it's only on your last 2600 corners, so obviously you didn't improve that much only your corners per incident rate to warrant more of an SR gain...
It's not broken, it's working as designed. Creating a system to detect fault would take forever and have as many, if not more, complaints than the current system. I mean, I'd say in most incidents people could do more to avoid crashing into those who've spun etc, so making a system to absolve people behind who crash into spun cars of blame wouldn't be a good idea. It's not the best currently but it's decent enough, putting avoiding crashes as the responsibility of both parties.
Week 13 only has 1 official series in both road and oval, for the entire userbase to drive in. Of course, that is going to put a lot of people together who wouldn't normally race in the same series - namely complete rookies and class A drivers. I actually boosted my road iRating/SR last week 13, by qualifying well, and staying out of the incidents.
In general though you need to drive smart in iRacing, and assume everyone else is an idiot - plus if you're constantly getting into crashes then perhaps you need to look at your own driving
