I have a question. I understand the notion that people who previously did not like Mayor Walker disliked him before the accusation and that explains why his performance rating did not change. However, my question is don't you have to make the assumption then that for the remaining people, the people who consider Mayor Walker as good/excellent, that the accusation had zero impact on his performance rating? Is that what the last sentence is implying?

Great explanation video JY.

I was in a similar boat. I started to drill from PT 1-PT18 (old format) since those PTs aren't included in the new PTs. One can argue that it is not the best option since they are older tests, but the questions are still testing the same set of skills.
