What are your current Program settings and XFAI target date?
What is your current status stars count?
iOS app deficit/surplus currently reflects XATA (fixed ramp rate) rather than XFAI (variable ramp rate). Refer to XO (xertonline.com) Training page for daily advice when using XFAI. A pending update to the iOS app will resolve this issue.
Since you are just starting out, I’d recommend XATA Continuous set to GC Specialist and Moderate-1 Improvement Rate while you learn more about how Xert works. That means the calendar will be blank but there is “plan logic” running in background.
Ride as you please for a couple weeks then experiment with XFAI forecasts.
You can switch back and forth between program types at any time or recast XFAI with different settings and note the differences.
For quick answers I suggest you search this forum. For example, why a large deficit may appear.
Or use your favorite search engine and include “Xert”.
