I changed when i adjusted the wing
I was doing low setting until the 4th turn( changed it to high on the second long straight.) Then back to low for the start finish line.

That lap was done all on high wing apart from the long straight after turn one which was low. Changing the wing to high before that tight right hander allowed me to be on the brakes stupidly late.

The adrenaline was going and i slowed for the last series of turns as i didn't want to loose it.
