does this mean i should walk outside? Or does it mean IF i am outside, the sun should only be to my back. It sounds to me like i should collect a sample, and then walk outside to do the test...
Correct, take a sample walk outside, have the sun to your back, hold the vial at waist level, add CYA wait for dot to disappear. You can pour the mixture back into the squirt bottle and repeat test several times to confirm the number.
