Goals and Prep
I'm looking at the track map. And, actually now there are no blank spots in my memory. It used to be that some of the corners I really didn't remember exactly where I started my turn-in, or even what I would be looking at. But now it's pretty clear.

That's an improvement in itself.

That point I went off into the lake, it was a combination of two (2) things; 1) I got excited that I made the pass, and then stopped focusing up the track. But, second 2) and more importantly, I wasn't prepared to use the speed I exited with.

I made the pass and exited the corner way above the other guy (at least 2 bike-lengths, I looked back). When I got over to the right edge of the track I wasn't prepared to make the hard countersteer needed to go through T2.

Recollecting all the turns on the track, I can tell where I'm being lazy. T9 and T10 I'm especially lazy on right now, and tend to just relax on those until the setup for T11.

I can also tell that I'm turning in a little too slow on T13, as it seems I'm always about 2 feet away from the apex. Additionally, I could let the rear wheel do a lot more work on the T13 exit, setting up for T14.

I carry a lot of corner speed into T13, but I tend to let it bleed off most of the time, and just wait for the exit before I pick the throttle up again with that corner.

I saw how I pulled away from ybslow in that video at the beginning of T13, but after I hit the apex he seemed to really pour on the speed while I was still slowing down.

And, then of course, I'm doing a lot of engine braking before I even start to apply the brakes entering T13 and T1.

So, these are the things I'll be working on my next track day.
 - stop relaxing on the chicane, especially at the end
 - quicker turn-in on 13
 - pick-up the throttle earlier after turn-in
 - don't get off the throttle unless braking on entrance to T13, T1.
 - find markers for downshift, throttle-off, braking, turn-in, hard turn-in, throttle-on, and up-shift
 - set your speed properly for 13 and 1.
