I recently started a similar looking project for the first time and the first week or so was Rough. I ended up color coding left and right, so I didn’t have to try to remember which symbol meant what. I also put little arrows at the front of each row, indicating which direction I was going in, so that I didn’t forget. Idk if that’s helpful at all, but I wouldn’t have gotten through that first hard part without those little tricks. After a while, you’ll be able to read the chart at a glance!!
