I also don't follow the week very closely, I use the guide more like a checklist, since I usually don't have the time to repeat the daily exercices (I wish I did, but alas, just not enough time), but I will try to do them at least once, and since I do them once, I usually elaborate on them a bit more, like, I'll add shadowing when only lineart is required, or do a few more of the exercice.
And on the notes side, I agree, I usually just watch the video completly (usually on multiple sitting), and then skip back to take notes on sections that might be worth exploring.
For example, for Anatomy, it can be rough to remember all parts or names, and going back and forth on the video would take time, so I just created my own little cheat map to check while doing the exercices.
Whatever works for you as long as you benefit from the lessons.
