That's understandable. But I still don't think there's a general guideline for what's a good daily or weekly TSS to aim for, I think that value is going to be entirely dependent on an individual's fitness level.
So in that case, since you've just recently got your power meter, one thing you can do is just ride as you normally do for a couple of weeks, taking note of the average TSS values for your easy and hard rides. Those can be your baseline to refer to for your longer term fitness plans.
