"Glanced at speedo (#2.5)" you stated above.
Fencer glad your walked away and could continue to ride. You were fortunate. By no means am I able to critique the actions that you took, but as a Novice Track rider on my R1, when my instructor at the FastTrackRiders School told me, keep looking ahead, never behind and DON'T look at the speedometer. Just opens up a chance to lose you focus on an upcoming turn. FYI, I ride at the former Fontana Speedway, now AAA Speedway in southern CA. We run on an AMA 2.3mile 21 turn course with a very high speed straight about .8 miles banked at 14* with a slight left bend in it. I only looked down at the speed needle once and will never do that again. Each time I go to the track I am reminding myself over and over to "Ride my Own Ride" I know I may never reached the level of the best racers out there. Good luck and keep riding while always looking forward and never behind.
