Took a look at the test - just for interest from reader only - while I don't usually mind, but you can always tell when a writer does the "insert myself here" in light parts of a story.  Of course, many writers also use horrible personal experiences when exploring very dark themes, but that is a very different thing. 

"Well, writers are pretty much inserting themselves all the time, at least I am. :)"

But there is a difference from using your experience from life for analysis of the themes you are exploring in your story and how some writers draw on how they would like the character to act to suit the personal likes and desires.  I don't mean to suggest that it is necessarily a bad thing, sometimes it works to great effect, just that it makes for a very different treatment and quality.

Of course you have to understand that I am not a writer - so my understanding of what writers draw on is totally limited.
