You keep comparing current Pennsylvania polling with the
final average from 2016.
By October 4, 2016, Clinton was +7.5, in Pennsylvania, per RCP.
On August 25, 2016, in PA, Clinton was +9.2
On October 10, 2016 in PA, Clinton was back to +9.2
As you can tell from the RCP graph, the last week of September was not characteristic of Clinton's PA lead in 2016.

Trump's current PA lead is +4.3. Comparing this to the last week in September 2016 is extremely misleading. As is obvious by the RCP graph.
