Off analysis please, Rennlist Braintrust!
Turn is a high speed sweeper left. I was increasing speed lap by lap to find the limit, and went off this lap. My initial thinking after the session, just based on my memory, was that I had found and exceeded the limit. After looking at the video, I think that I was just nervous and off line. Watching the video my impression is "Turned in too early, early apex, so ran out of track on track out...."
Lots of folks here with more experience - what do you think?
Thanks!

Buy a lotto ticket... that couldn't have ended any better.
I don't know this series of corners but your entry does look early shortening your track out options. Your entry speed also appears high... you brake early then balance throttle on your entry... but your tach is continuously decreasing as you turn in... rotation is induced and aided by trailing throttle... tires already squealing at or near the limit... you mini correct mid corner but simply not enough track to work with and run off.
Perhaps later entry, better arc, and more maintenance throttle to plant the rear will put to you track right just before the next sharp left hander.

Look at your steering input. You are actually adding steering input at the inside curbing which means you turned in early. Most importantly, I think you were going exactly where you were looking.
Nice recovery!

Thanks to all for your analysis! Since I was working on speed through the corner, I was hoping that the mistake was trying too much speed, which is sort of a cool, big ***** mistake. Sadly, I agree that it was early turn-in/apex, which is sort of a rookie/dumbass mistake. I don't expect to be perfect, but I am hoping to at least move up to a better class of mistakes.....
I really like as much data and video as possible. Mostly I delete it, but sometimes it is illuminating. Based just on my memory, I would have recorded the off as a speed problem. Looking at the video, it is clearly a line problem.
One of the key things I learned at RL on watching video is to ignore what is going on through the windshield when reviewing a turn, and watch instead the steering wheel, looking to see if the driver tries to increase input after turn in (like me way too often...). I forgot to put my tape strip on the wheel at 12:00, which makes it even easier to watch the motion.
In looking at the video, I can also see a clear trail into the curve on the correct line way ahead of where I was. I should be able to register that real-time while driving and use it to help avoid mistakes like this!
I was in a Suzuki Swift from our friends at Rent4Ring, with 135 thundering horsepower. I should have mentioned, it is a front wheel drive, first I have ever driven on track. My 911 reflexes, trailbraking and especially going to power mid curve to rotate the car, were my enemies - just induced understeer... R4R said that it is a 8:30 car if driven well. I was doing consistent 9:35's when traffic was not bad, and know I had an easy 10 seconds I could get, but have no idea where the next 50 would come from.
When traveling for business, I try to get on track where I can. I run Harry's on the phone, put a GoPro behind me to watch the driver, and a helmet cam to see where my eyes are going. Mostly everything is deleted at the end of the weekend, except for key data (corner speeds, etc.) and "interesting" video, like this off. In this case, the phone ran out of memory, the GoPro battery died, so the helmet cam was the only evidence I had to review. Triple redundancy sounds like overkill, but it has helped me multiple times!

Ah, there is the problem. You didn't have the benefit of following Viperdude at this point on the track. He would have schooled you the trick of not worrying about going off is to go so slow through the corners such that early, late, on apex, off apex, etc don't matter. Then, and this is the sooper secret part, you unleash your 500+ horses on the straight by pressing on the loud pedal. Rinse and repeat:
Of course, you also have to be self centered enough to ignore that guy in the hamster powered tin can filling up your mirrors at every. single. corner.

That said, I don't think you can go in too fast into that very corner in a 135hp car, you just need to drive the right line.

God, I love that track.
