I'll throw my straw man out there:
- Race director arranges ahead of time for the course to be measured and certified the morning of the race.
- Measurer lays out short (100 meter) cal course on the race course surface.
- Measurer rides the course once and reports the distance(no SCPF) to race director. No adjustments to the course are made.
- Measurer completes SMALL application form that includes no map and sends it to state certifier.
- Certifier sends certificate to race director that states the distance and a statement that the certification was valid only for that race day.
- Only measurers that the state certifier has experience with and trusts would be eligible to perform this type of measurement.
Is it accurate to within 0.1%? Probably not.
Will some courses be shorter than what's reported? Yes, about 50% of them.
Will the course be more accurate that 99% of existing cross country courses? For sure.
