I have the 955 solar as my preferred training device and tracker I also own an edge 1040. The daily suggestions on the edge, for the next day are updating real time according to my exercise intensity during the day and condition. Example. If the suggested workout is base for the next day and today is recovery, if I train hard (bike ride on threshold, after the activity the edge will change the recommendations for the next day and the whole week immediately, while the watch will do the same at midnight. Why not have the watch updating the suggestions during the day as the edge does is that why true sync exists?
