I am using the TPR book as well. My question is that there are certain passages where I get 2-3 wrong, while I get 0-1 wrong on others. I do understand that I need to do efficient post-game analysis, but I tend to get discouraged when I do not see an increasing trend in my scores. I also have the EK book, but some of their rationales are convoluted. I am thinking of just using them for endurance. If anyone has any advice, I would greatly appreciate it. Thank you.
