According to my stats on my site
www.justsybians.com Webmaster area for now. which has one warning page, six tour pages, the join page, as well as the 2257 page.
Stat breakdown (rounded off) shows:
85% go through whole tour.
10% go from warning to first page to join.
5% hop around. Meaning they visit first page of tour look at join, go back to tour watch samples, go back to join, check more videos, then join.
Oddly almost 1% click the 2257 link before going back to the tour.
About 30% of the video samples are watched by the majority.
