The cal course is 1000.0 ft. regardless of the temperature on the day the course is used.
The constant, without the SCPF is 3590.75 counts times (5280/1000) = 18959.16 count/mi
The course is 497825 counts
The length is 497825 counts / 18959.16 counts / mi = 26.2577561 mi
A marathon is 26.21876 mi
The course validated is 0.03899615 mi (205.899 ft) long
The constant with the SCPF is 3590.75 times (5280/1000) times 1.001 = 18978.1192 counts/mi
The course length is 497825 count / 18978.1192 counts/mi = 26.2315246 mi
A marathon is 26.21876 mi
The course measured using the SCPF is 0.01276462 mi (67.3919 ft) long
The question is “What would you report as the course length?”
I would report 26.22577561 mi as the validated course length.
