Base progression

All - I am a bit confused with what I see.

I am about to end ss b2 lv, but when I now go to trainingsplans - ss b lv on the website it seems these workouts are much harder then what I did. Is this because this already takes into account what I did recently and keeps progressing?

Eg Leconte thresshold 5.9 is scheduled today while dragon threshold 5.5 is included in the first week of lv ss b1.

Yes. When you look at training plans it takes your current progression levels (PL) and creates a training block. So as your PLs change the plans change accordingly.
