I’ve used IG in the past, not currently.
The general stack idea I try to follow is to run the sub or sub combo and wait for a manifestation or take action toward a manifestation. Then when that happens, play a loop of a different sub to focus the evolution of the manifestation in a specific, altered direction.
For example, recently used KB which brought about assistance in manifesting more information I needed about my development with that. Next step: run a loop or two or Limitless or related subs to improve the ability to absorb the new information. Next step may loop (back to KB) or move in a different direction like UWX for expressing insights from that process in a written form. Periodic reinforcement of the prior primary subs. Until end result is reached. That’s the theory, anyway.
One example after some time of using IG was for a period I added GLM which improved drive to get my task done at the time (a tutorial writeup on using a Rust library), for a period of about a week or so in the stack before rotating it out.
I’ve found myself experientially that short runs or rotating subs within a stack tends to work for me, I don’t know how others have found it though. Its kind of like a way of adding short/micro loops to add color to the primary.
