Keep in mind though, the reason to go out-in-out is to maximize the radius of a corner, minimizing scrub. Other factors like banking will modify that.
And a strictly semantic correction to an earlier comment here; outside is faster, inside is quicker.

Perhaps think Carousel (outer loop) at Watkins Glen vs. Lightbulb, another high speed highly cambered turn. How do you drive that?
For me it was about the same way. Entered low, held it fairly tight all the way through, let the car go out where it wanted to be. Looking at my video the entry was about 6-8 feet "out" which put me on the edge of the asphalt by 1/3 of the way in..

Interesting comments regarding the best line into the lightbulb turn. The out-in-out seemed the fastest and most efficient but without a data read I can't prove it. I do know that having at least 2/3 throttle 1/2 way just prior to the apex and full thru track out seemed to provide the biggest gap to those behind me. I look forward to someone sharing data proving what is truly the fastest line....

Driving a F stock car requires me to maintain as much momentum as possible entering the front straight.

I suspect driving a 962 would be similar.

Did the same during the JSR D.E. while trying to get on it a little earlier each time to increase my exit speed and experienced the corresponding increase in pucker factor tracking out on to the straight.

Check that clip I posted and you'll see that I was outpowered but not outpaced. Firehawk and I also spent a fair amount of time together, but I think we'd have had better racing in the group with the E Class cars.

Indeed. Some cars just recover better from loss of momentum than others.

A man after my own heart. The shortest distance can often be fastest and Unothodox. The clock does not lie. I love when people question my line but not the my times. Great job Charlie! We are not in DE anymore. Yes they are all momentum cars!!!!! If you are not stuffing it into the corner you are probably going too slow. IMHO

Bull,

Of course it's all relative. I'm sure Alonso and Hamilton are out there hoping Kimi (or whichever Ferrari driving is leading the race) has a hiccup. And, there's really no such thing as a "momentum car". Assuming that the idea of racing anything is to get around the track faster than everyone else, a disruption of (forward) momentum ain't good.

Still, there is always the need to slow the car and to regain velocity, so I understand what Joe (our Firehawk friend) was describing too, and there's no need, really, to be reminded here that all racers seek to maximize exit speed to the end.
