Xert-O-Meter Colors

On the Android player (on Activity page), there’s the dial that shows current watt output with a pointer to a colored dial. The dial goes from green to cyan (light blue) to grey to yellow to red. I understand green, yellow and red but not the other two colors. Can someone explain?

See the explanation in the FAQ for the Remote Player. It’s the same. Green = below LTP, Blue = below TP.

What about the “grey” band that comes after TP to the start of the Yellow. The FAQ does not address this. It says:

30s Power and higher – Red Band
3min Power and higher – Yellow Band
Lower Threshold Power to FTP – Blue Band
Below Lower Threshold Power – Green Band

Grey is what is left: above TP and less than 3 minute power.
