I wouldn’t stress about maintaining your TSS consistency as you go back to plans
Do the first few weeks of SSBMV and see how you are responding. If, any only if, you are adapting well and feel fully recovered, should you consider adding additional rides
If you get that far and want to add some TSS fillers then I’d suggest you’re better off extending the rides already in the plan. Add 15 minutes at an endurance pace to the end of a few rides each week and you can pretty quickly get bonus TSS and kJ
