You can just edit your Patrick score variable with a RenPy save editor... Do it at the very end of EP10 or at the very beginning of EP11 saves. Replaying game for a bunch of times for the sake of one variable is definitely not worth it. As much as I like this game, I wouldn't do it if I were in your shoes. After editing your save files with editor, put it in your game saves dir, load & resave and you're fine. DPC is still using the old & outdated RenPy engine for BADIK (v7.4.10), but even 8.x.x versions works perfectly after you edit your saves.
