Coach notes

Founder practice standards: blocks to H1 touchdown 2.80 unacceptable, 2.50 very good, goal into the 2.4s. H1 to H2 in the low 1.0s, otherwise the Slide. Later intervals 0.99 or faster.
The proposed race scorecard is accumulated flight time and accumulated ground-contact time; instrumentation is open.

Unresolved How left-left and accumulated contact and flight times are to be measured.

Timing Standards -- The founder's practice numbers for blocks to H1 and the hurdle intervals.
The Slide -- Each interval faster than the last, until max velocity, then hold it ideally through H9.
The ABCs -- Three block starts over discounted spacing, tightening toward race spacing. The first splits of the practice.
