Can't Keep up to xss even on moderate 1

ATP = TED is a phased progression.

ATP = Continuous is either floating (Maintenance) at your current TL and selected focus type or pushing yourself with a ramp rate > 0. Since you are not following a progression you can decide which direction(s) you want to take things, adjusting settings like IR and athlete type along the way.

What is your current status stars count and weekly TL number (from Weekly Stats under Planner tab)? If you started high, close to the max hours you can commit to, then even Moderate-1 will be difficult to maintain. However, you can improve fitness with IR set to Maintenance by designing your own blocks within that schedule. You can use the Planner and switch things up week to week.

The higher the starting count/TL the more blue/fresh form is expected with higher intensity workouts recommended. You can use the Freshness Feedback slider to dial things down if not feeling as fresh as the predictions.

You are in charge of any periodization you wish to apply (3/1, 2/1, X days on/X days off) or any weekly allocation you wish to follow such as Mondays off, Tue/Fri hard, Saturday long/easy, Sun group ride. XATA will learn that pattern and recommendations will reflect it in future weeks (ex. Advice is based on your recent activities performed on Fridays). Otherwise XATA will even out the hours as you are experiencing. You can use Filter to change duration or simply ride longer/shorter as you are able day to day. XATA adapts to whatever you decide to do.
If you are not following a regular weekly pattern the pacer needle will keep you on track based on the rolling weighted average over the last seven days versus what you plan to do in near future.
