> You can now choose to display average DFA a1, starting W’bal, ending W’bal and W’bal delta for intervals. Click Fields under the activity timeline chart. Note that DFA a1 is only displayed if the “Alpha1” is present in the fit file. Calculating this from HRV data is (high) on the todo list. Also you need to re-analyse old activities to get the W’bal fields for intervals. [Screen Shot 2022-02-12 at 15.00.56] [Screen Shot 2022-02-12 at 14.59.39] [Screen Shot 2022-02-12 at 14.54.40]
