I mention this problem in one of the previous posts - with high restrictions you cannot e.g. enter server statistics, because the required time is (under default Airio settings) impossible to make.
To solve this I've added into 2.1.2 a new configuration item. When you specify there a handicap (car or track/car combo), you may also specify in percents how much slower could that car be.
Example: If you set UFR to always have intake restriction of 25 percent, you may also specify that the minimum required time should be raised by 10 percent.
I plan to add some more things into 2.1.2, test it and release. I'll need a few days for that.
Right, I see what you mean. Unfortunately this is not currently possible (unless you run two instances of Airio, naturally). The core concern are the common statistics, shared between all connected servers. Because they are common, all servers should use the same settings to accumulate them.
So, if you currently set a 20 percent restriction for UFR, it will be applied on all servers and all gathered stats will be compatible, done under the same conditions, results comparable. If you could set restriction to 0 on one server and to 20 on another, the stats would be mixed and you'll have no way to know which cars used approximately the same settings as yours.
Well, I hope you see what I mean. But I'll think about this, what could be done...
