Observations

Computed
  • Run 1 is typically +6.00% off the PAX winner; Jeff finishes around +2.25%, so about 3.8 points come over the remaining runs.
  • Jeff is typically within 1 point of final pace by run 3.
  • Median gap went from +1.79% in the first half of these events to +3.38% in the second half.
  • 1.9 cones per event. Each cone is 2 s, about 3–4% on a 55 s course.
  • Run 5 is where mistakes happen most: 50% of run 5s were coned or DNF.
  • 1 coned run was faster than the time that counted. The biggest, at SPK #10, would have been 0.572 s quicker and 5 PAX places higher clean.
