What do the colors blue, green, yellow, red correspond to on the gradient color overlay.
I want to know that
- blue is less than 4% (guessing),
- green is 5% to 8% (guess)
- yellow is 9% to 12% (guess)
- red is 13%
Are the colors relative to the ride baseline?
If so, how can I calculate the gradient value per color for my route?
