Never heard of a single group holding 20+ meetings a week, seems reasonable to me that it would be subdivided into smaller groups for manageability. As far as AA literature goes, theres a pamphlet on groups.. https://onlineliterature.aa.org/The-A.A.-Group. Dont know if it would answer your question any better. People move to different home groups all the time - its really up to you.  For me, the people are the reason I stay in a group - I formed a deep attachment with some of the people in my home group early on in sobriety, then moved about 20 miles away. Never could find another group that I shared a similar attachment with, although I have called one nearby group my home group for years I still occasionally visit the other one and I connect with some of its members online.  Some groups will say that you have to attend business meetings to be considered a home group member.  Others will say youre a home group member if you say you are. I have become less interested in business meetings over time, the politics is not something I enjoy much. Too many egos, too easy to get my own ego going.  If you are that unhappy with the group conscience, it could be a good opportunity to practice the Serenity Prayer - accept what you cant change, decide whether you want to change which home group you attend or just change your involvement within the group you are in, or change your attitude toward it, or change nothing and continue to advocate your view.  One thing is for sure - your home group will change over time, with or without your input - and time will tell in what ways it changes.  Many people will leave, many more will come, and a few will stay (or leave and come back later). For me, its the other people who bring me back - not the structure of the meeting. But thats just me. To thine own self be true!
