Tjapukai, doing the active exercise for half an hour every day, especially at the same time, is better than doing an hour 3 or 4 times a week. The value of regularity and commitment should not be under estimated.
You don't have to do all of the exercises in the active meditations. Do a few today and a few tomorrow. Work and regularity in your practice.
If you are have not experienced any of the benefits from SFQ. Review the material again. I would suggest to you to learn the meditations well enough that you can do them without Master Lin's guidance, and just use the meditation music, or silence. Once you can do this I would suggest, for you, that you spend more time at the beginning in the starting to meditation for a few sessions. Specifically the combining with the universe, going into the emptiness, and calling on your master.
This is what I feel you need to work on. As a closing you are not doing anything wrong. It is a matter of moving along the continuum of good, better, best.
You are perfection.
