I recently noticed some things comparing iRacing to real life. I practiced COTA a bunch on my budget iRacing rig pre track day. Ton of bumps at COTA in real life that weren't in the sim. I guess they weren't there when the track was scanned. Couple slight variations in lines that work.
That being said. Loved that I had iRacing as a preparation tool. I was right on my pace for my current skill level set, first session out.

I recommend for drivers preparing on a sim for an upcoming race to constantly change the weather so they don't become used to an exact line and start driving too much by memory.

What would be far more informative, objective and telling would be a serious analysis of the gSum, sector times, grip analysis, brake pressure and throttle position absolute values, as well as their relationship to one another on Chris' laps.
Only then can one even begin to say that what Chris did was "at the limit." More likely, it might (and probably would) show opportunities for improvement, which is in the end is what we ALL want.
There is NO car that CANNOT be driven faster, period.
Lastly, the idea of different lines for different experience levels is fundamentally incorrect, in order to achieve the most optimum results.
Teaching conflicting geometries and variable approaches and techniques sews confusion and prevents optimal formulation, development and execution of fundamental skills, all of which contribute to the optimal performance by any driver, in any car, on any track.
Apologies to Joe. This thread has well and truly left the paved surface...

COTA indeed continues to get bumpier and bumpier in more and more places.
However, it's not due to construction. It's due to the natural expansion and contraction of the clay amalgam soil of the area with extreme drought and flood cycles.
It's disappointing considering how much care was taken during construction, and how deep the base for the track was dug.

Then, start a new thread on "different approaches to driving Lime Rock Park."
Rennlist IS an "honest debate."

but the #1 thing is ive found to get faster is to use a coach like the great coaches up here. when yo ufactor in the cost of tires, running, support...a coach to help you get faster is the best investment you can make.
I've worked with a few up here and respect them all and find them to be a great way to make a great day at the track better.
good coaches don't operate in a science lab but consider so many different factors, the most important probably being the car, conditions and me, the driver. some drivers are great trail brakers so maybe they can try stuff others cant. some can handle cars that are very loose while others like a tighter car. most of amateur drivers struggle with giving great feedback to the coaches, to the crew. so sometimes a coach is great for me since i can talk to them about what i was feeling, how the car was handling, where i think i could do better...they can digest that, review the data, and speak the right ideas to the crew who can implement some changes.
this thread was about the value of coaching. could not agree more. wish i used a coach more often. sometimes i just like not using a coach ,but I'm always faster with a coach.
here are two vids : the gbt2 lap which was pretty ok
the GTa2 lap.
btw, classic example of changing things based on car condition. that gta2 run was like 2 yeasr ago? was like 34 degrees everyone in winter jackets, snowflakes in the air. i think the car had another full 1second in it, just was not comfy motoring too much through the turns but rather just carried a bit more momentum into them and tried to be smoother on and off the throttle given the temps. it was legit flurrying at the grid.
trust in the coaches. they can help. if you can afford it and want it, you cant go wrong.
