2017 Fall Qn13 and 2019 Spring Qn 7
I am confused how to identify trending period when trending premium. When do I use Avg Earned Date and when do I use Avg Written Date?
For instance,
2017 Fall Qn13 Avg Earned Date is used
2019 Spring Qn 7 Avg Written Date is used

Did you mean to reference 2017-Fall Q13? The screen shot didn't seem to match that question.
But in any case, for 1-step trending, you should get the same trend period regardless of whether you base the trend period calculation on earned or written dates. See this section in the wiki:
