When you're watching your replay I'm 99% sure that you will have a perfect comparison.Well, it shows you steering the same way in the replay too, so I guess there's 1:1 match with the virtual wheel. My point was that you needed to steer less, not more. The amount of steering needed could be somewhat setup-dependent, but even with a rather safe default setup you don't need to turn the wheel that much. You can clearly hear the fronts scrubbing away the speed. And the induced understeer forces you to lift off where otherwise you might not have to. I see that you could not take the Kink flatout on fresh tires in quali while that feat should be doable in the Audi even on worn tires in the race.
The only times I might do that kind of steering is when I really need to warm the front tires before starting a flying lap in quali because in some track/weather combos fronts just don't heat up enough when driving normally. But that's only good when I can throw away the lap I'm doing it on because it comes with a big time loss.
You probably got used to steer that way and it might be very hard for you to avoid doing it, but if you invest some time into re-learning this you should eventually see your lap times getting better (after they get worse initially). AC gives a very nice feeling of the limit when you rotate the wheel. The force you feel goes up and up until you turn it too much and after this point it decreases because the fronts tires basically start sliding and give less resistance to turning them.
The replay data only stores the steering degree of the car, not some virtual settings or whatever the user's wheels make of it.
How much more does he turn in your replay?
