From there it's personal preference, if you want to look like Ben Spies and try to drag elbow. unforunately you cannot fully appreicate this until you go to the track and expience it at full speed.
I thought I was close, but pictures said I was still 8"+ away
But I agree with ya, I barely leaned the bike over at all on the street, I learned 99.5% of my cornering skills (or lack there of) at the track. I only had a few months of riding under my belt before I got out to the track, so it's not like you need to be close to knee-dragging to get out there
As long as you can effectively turn and control the bike, you will be fine out at the track

(helmet gives it away)
