Thanks for your opinion, "now go get your own car and we'll see how you do in a crowd." 
j/k had to use a Days of Thunder quote. But what I mean is I am assuming your critiques come from experience in a SM on track. The speed and grip levels achieved in the L are so far beyond a SM, my Grand Am car etc, you can't drive the same line at all. But to respond to your individual points...
Yes!!!
As far as the entry curbing goes, let me assure you it would not be faster in the L. You are going so fast at that point the time you would gain from getting 1 foot wider for the turn would not make up for how much you would upset the chassis going in to the turn. In a slower car, even the Legacy, you can to a point use that entry curbing and have it be beneficial.
As far as the exit curbing goes, well I am only human, and having only about 8 laps before the laps you see in the video ever in the L at Laguna, you need to leave yourself room for error. With more time and chassis setup on the track I would for sure use more and more of the overrun.
-in 6, I don't hear the car get back on the power until past the apex? the runoff is surprisingly benign if you just drop one wheel! definitely try to use that extra 2 feet that the exit curb gives you... it might just give you the edge you need next time! I find you can carry an extra 2mph through that corner using that exit curb... precious real estate IMO.
What you here in the video is the turbo lag. I am acutally back on the gas before turn in, but you don't here anything until the turbo comes back in and the engine starts making power again. Concerning the overrun, see point above.
-nice line through the corkscrew with such a powerful car! nice line through 9 and 10 as well! the entry to 9 looks very well-executed. 10 I imagine is pretty difficult to get right because you don't want to park the car too early at corner entry but going in too hot would be worse (I think I saw a pic of the car off-roading at the exit of 10 yesterday).
Thanks!
The run from 10-11 goes by really fast, and I love downshifting through three gears hard on the brakes in that car, very fun!

-it seems like you're leaving a some room in T4 with the entry curbing and exit curbing. I find the entry curbing helps to actually carry more speed through that corner... give it a try and see if it's beneficial on data. also in 5, I find it beneficial to use the entry curbing and the exit curbing there. however some don't like to use the entry curbing on the right since it causes braking issues on cars that suffer from bad knockback.

I've driven those Hankook Z214's and found them to be about two or three 20min session tires before they're junk. Do you have the same experience? (I've run the C70 soft compound.)
Edit: Hey, just a thought... would it help to left foot brake or use some other sort of boost trickery to get on the turbo earlier exiting 6?
P.S. toss me the keys for a session pretty please.

Thanks for your feedback. It's interesting to find out your perspective of driving the course in an incredibly fast time attack subaru. I'm sure driving it is quite different. I'd like to drive something like that in the near future. My experience is only with my stock STi, lower powered formula cars, and of course my SM. I didn't think the line would necessarily change at the entry to 3 or 4. I think in 4 you could absolutely be right because that "left" turn could potentially unsettle a car that needs to get on multiple hundred WHP an instant later.

All I will say about the Hankooks is that when we used them in USTCC we had a lot of trouble getting more than 4 good heat cycles on them. I am not sure if they have fixed that problem since then, but the Hankook Silvia seems to run fast enough.
Another interesting point in the setup of this car is we have found that we need to setup it up fairly stiff for its weight. This is because we run so much aero on the car we need the spring rate at high speeds or the car squats to much. This leaves the car fairly non compliant for hitting overruns, even smooth ones with just the groves in them.
The weal amewican hewo!
