your posts are great. I am glad that you didn't get defensive, and accepted criticism. Your initial post also shows that you have a very active, analytical mind. That is an asset to you as a player, and if you keep at it and put in work, you will develop well with that attribute. You also have a grasp of math, even if you are applying it incorrectly in the wrong spots, that will help you immensely as you learn what to apply it to. I also like the math, and like to do crazy numbers stuff with the game. Since playing cards is such an individual journey, pretty much everyone starts out reading a lot of stuff, going off in a lot of different directions, and then finally finding their way to a path where they are developing in a good way in an objective sense.
stuff for you to work on with fundamentals :
pokersnowie preflop advisor : This is an awesome (free!) tool to look at preflop spots. It is completely free, and you will be given good guidelines about what to play in what position facing a certain action. You can adjust wider or tighter, but they are a good way to start visualising what baseline, average ranges do and should look like in today's game.
GTO+ : if you spend 75 dollars on this, and start plugging in snowie ranges for preflop and solving spots, you will develop a lot more rapidly than you otherwise would be able to. I can't stress enough how useful this is for people who like to analyze the game. As you are working, you should still be simplifying, as although you are working with some big ranges sometimes, you will notice big patterns that you can latch onto. IE, this range is not leading middle pair in this spot, and is always check calling it. It doesn't want to checkraise that hand, it wants to checkraise something else with less showdown value, like this other hand etc. etc. This also comes with the caveat that if you don't know what you are doing, you can get some misleading results, but if you have any questions about how to solve a certain spot or what sizings you should use for a solve, you can always ask those on a forum like this one, and there is a lot of info on that as well.

peter clarke is probably the best content creator for beginners imo. He also wrote a book called "The Grinder's Manual", which is worth every penny and more. He explains things concisely and simply, and goes into theory, but in a very practical way. He also has a course on RIO for beginners which comes with a free month of RIO essential, the course is great for beginners, and is a great starting point for 6max cash.
good luck, and continue posting hands that trouble you!
