This is a subtle question.
Because knowledge is funny.
It can be immediately applicable. As when a teacher or coach corrects your form. This knowledge-based adjustment leads to an immediate improvement in practical effectiveness.
It can be applicable in the mid-term. As when a better understanding of developmental principles enables you to set up a better training program for the next 2-5 months. This can streamline your growth process, though you won’t see the effects until 6 months from now.
It can be applicable in the long-term. As when, for example, you gain a clearer understanding of how your practices relate, in the bigger picture, to practices that you may not even be considering yet. This can help you to plan and direct your growth over time.
And then some knowledge seems to not be very applicable at all. It’s just interesting. 
My favorite knowledge is experiential. And I’ve found that this is definitely getting enhanced by Sage Immortal as well.
For example, for the previous 2 to 3 weeks, I found myself spontaneously doing a kind of kinesthetic/somatic/vestibular movement practice with my eyes closed. I found it helpful. That was an intuitive practice. I didn’t get it directly from any of the teachers, but it was still inspired by connections that they helped me to make.
Sage Immortal helps with both experiential knowledge and informational knowledge. Not just one.
My path is similar to yours but not identical.
The truth is the way I practice is exactly like what is described in Revelation of Mind/Revelation of Spirit.
I don’t want to become “better” at anything. I don’t think there’s anything wrong with practicing to become better. But it’s just not where my heart is.
This is just me personally. I don’t think my way is best for everyone. I didn’t even choose my way. It’s just my soul. And your soul is yours. And it’s perfect.
Anyway, for me: I practice as a way of aligning to the What Is.
And that’s it.
Better. Worse. Meh.
A person could practice to an amazing degree and then unfortunately get injured in an accident. And then what? Should they feel terrible and give up practice because they’re not a master anymore?
I say no way.
The beauty, for me, lies in what we we orient towards.
The way I put it is like this:
Every plant tries to grow towards the Sun. But if they were to actually reach the Sun, what do you think would happen?
It’s in the ‘reaching towards’ that I find what I seek. The opening.
Okay. Anyway.
Back to the point:
What you’re describing is The Alchemist. It’ll give you that direct boost and support to your spiritual practices.
For becoming better at meditation: The Single Point, Metamorphosis, The Alchemist and others
For being steady and committed to Yoga: The Alchemist, Avatar, Metamorphosis, Foundation and others
For revealing hidden knowledge about yourself and the Universe and being guided towards spiritual mastery: The Alchemist, Sage Immortal, Revelation of Mind, Revelation of Spirit, The Flow, The Wonder, Spiritual Freedom, and then so many of those modules from the Alexandria module pack. Haven’t memorized those yet.
Although I’m not strictly goal oriented, but I do relate to your goals. My own custom has a similar focus.
Anyway, you’ll find an excellent way that may or may not look anything like mine. When you do, I look forward to learning from you.
