    Hmmm... to what class does said pencil belong and is the pencil on street tires or r-comps?

    That looks like the basic idea. You'll find many folks do that inside twisty bit a little different each lap...its tricky and there are different lines based on driving style. The biggest thing that jumps out is the bottom right corner of the pic (turn 4?) is crowned and off camber way out there to the right where the pencil line is. That can make the car loose when getting back on power for the back straight.

        Turn in later on T1, it's banked and everyone is afraid of it for no reason. Turn in at the last brake marker and high 5 some cones.

          Turn in early. Banking holds you down low. Plenty of room to track out. Turn in too late and the banks spit you out.

          All depends on vehicle balance.

              No, no. Turn in at just the RIGHT time!

                On skid pad, turn in a bit later and apex should be down on left side of pavement. about halfway thru. Your pencil shows you mostly being on the outer right side of the skid pad which is in the region where the camber drops off.

                If you do turn in at the right point, you should be able to set the steering wheel in one position and hold it steady all the way round. It will bring you down into the apex and track out to the right side gators and continue on toward T5.

                  No, no, no, it's turn in early as late as possible.

                    Thanks, Rod it was nice meeting you

                    Here's a revised version after going over the map at the track with Craig and Brett.
                    Also I was able to go out at a reduced pace on my last session last Saturday and feel the camber in T2 & T4. Get on the good side of the crown and you'll be rewarded with way more grip. The only trouble is the debris on the edge where you turn in.

                      Turn 3. I hate it. I have so much trouble getting to the apex. Staying out there on the edge is difficult for me as well.

                      I've tried diamonding it to save all that distance but that didn't work too good for me. Shelton tried it with some success.
