Does SBR's archived closing lines for 1half, and 1st q - 4th q reflect knowledge of the team that is going to be receiving the ball?

i am backtesting and it looks like i can beat opening lines and 5dimes lines but have a bad go against 1st quarter lines and 1st half lines which happen to be pinny closing lines. i can really use some help here if you will share your knowledge i am ignorant beginner.
