Here's some video from the NJ BMWCCA HPDE event at NJMP's Lightning track on Oct 15th. Session ended with a black flag due to a water-beetle problem in the light bulb.
Starts out fun, then there is a lull, but it picks up again at around the 15-16min mark. You can really see how an early point-by makes a huge diffference in momentum vs. having to park it behind someone to get the pass.
Disclaimer for driver performance: Was battling awful understeer due to poorly chosen staggered tire sizes.
