Large Font Power

3s Average Power in a super large font for edge 520 for those long-sighted folks like me with trouble reading the standard Garmin fonts, with additional help of top bar color codes for power zones. Secondary data is cadence in the largest available Garmin font - also with color coding. Both FTP and Target Cadence are user configurable.

Power Colors : zone1 less than or equal to ftp * 0.55 = Dark Gray zone2 less than or equal to ftp * 0.75 = Purple zone3 less than or equal to ftp * 0.90 = Blue zone4 less than or equal to ftp * 1.05 = Green zone5 less than or equal to ftp * 1.20 = Yellow zone6 less than or equal to ftp * 1.50 = Orange zone7 greater than ftp * 1.50 = Red Cadence Colors : Target Cadence +5 or -5 = Green. Low Cadence = Blue, High Cadence = Red
