For purposes of gathering information, did Abigail approach you on the day of the semifinals telling you to stream for a point boost? If this event didn't trigger you might be missing something in your current save. (Did you already complete the cow path? If this event didn't trigger, maybe Abigail needs the milk for the event to trigger?)
I have used the cheat engine on week 8 once the numbers are revealed to boost my score to at least a thousand past Erica, and it has always worked for me. I enjoy being able to have a degree of control over what happens to my character during the weekly events, especially the piercings, and so always keep my score low before then so that I don't have to reload the save and play the event a bajillion times.
