not sure I know what you mean
My "get in line" remark had two meanings:
1) Get in line, meaning, get in a race, and race...you will only lose your time reading about it...there is nothing you can read that will improve, except the regulations, and for that read the regulations...have you ever seen a book that teaches hoe to race NASCAR or Formula 1? I haven't
2) GEt in line also means...I am in a line waiting for such books, and so far nothing worth...
