Figure out missing data

Dear Forum/Support
Could you please advise me on the blue session (picture attached) I get the grey dropouts. If you watch carefully on the bottom of the screen you notice grey dropouts in between the blue area. I do not recall that I stopped cycling or the avatar was static. I don’t think I have Bluetooth interferences

Many thanks for your support
Best Regards

That is nothing to do with drop outs. The colours indicate levels of effort compared to your FTP. Grey (Recovery) Z1, Blue (Endurance) Z2, Green (Tempo) Z3, Orange (Threshold) Z4, Red (VO2 Max) Z5

Hello S Ticky,

Many thanks for your help
