One of the very first questions is what zone you are in. Hopefully they will take more consideration to those in canny and twine.
The sample is sent to a range of people of all experience levels in order to get a good representative sample. We then break the data out by experience levels when looking into the results.
People who are more experienced tend to fill in surveys more often, so we include that little bit of text about "only played once" to try to encourage the less experienced folks to also open up the survey.
