I don’t think my example is anything unreasonable, 15-20 seconds slower than what’s possible over just a few miles is a huge difference and often wouldn’t be near a properly good Rivals time at all even for a weak car.
I can’t possibly agree with what you said about an AI running away on a regular basis either simply because of my own first hand experiences, you’ve seen yourself I used to post my Trial races every week in the season thread when I did it properly, with a proper car I lost to an AI….once, and I could easily default to deeming that must have been a runaway because I drove well with a strong car + tune for 2 and a half laps of Estadio that I’d tested on there beforehand and only ended up right behind it at the finish.
What I’d be doing then though is discarding the fact I spent the opening half a lap faffing about with passing a clearly slower teammate too cautiously, I’m not exaggerating when I say that throughout my whole time with the game I’ve never had an AI in a Trial that I couldn’t possibly catch if I’ve had a proper car/tune and got the driving side right which I didn’t do there, occasionally I’ve had them in my 701PI attempts but there’s no basis for any complaints when I’ve made the choice to be 90 odd PI below them, their inconsistency is actually the only reason it’s even possible for me to do those, if they were consistent and went a pace befitting of the difficulty level the game claims they’re at in the Trial then a PI deficit as big as that wouldn’t be possible to make up.
