How long ago was your last BT event as indicated under your account name at xertonline.com?
Is that the activity you used to modify the signature?
As @wescaine mentions if you don’t plan on generating any BT events during Base you can change the Decay Method to No Decay and your signature will float up/down based only on training load changes.
Pre-base: there is no specific guidance used for the Focus of your training; the advisor simply offers a wider variety of workouts that are near your Athlete Type.
