I also play with lines and discover that regardless of corner entry or turn-in point, if there is a slower rider ahead, I can simply push the bike a bit further over and steer tighter and go underneath any bike I happen to come across.
Exiting the final corner I can choose where I want to be, even hugging the inside all the way around despite carrying incredible mid-corner speed. It is like there is more front tyre available in reserve there if needed at all times, a bit like insurance. This makes the bike very raceable.
