IME Xert has master’s plan logic built in. It’s called master of your own fate. 
Tweak the sliders as needed at any time. If XFAI is in play, recast (update) the plan.
You can also adjust Polarization Level and/or XSSR Preference to meet your needs.
I operate fine with the default settings but occasionally use Freshness Feedback when on XATA or Recovery Demands if an XFAI Goal starts to feel like too much.
I’ll also take two days off in a row whenever I feel stretched which typically occurs as I reach 4+ stars during the summer and put in some long hard days.
