My understanding was that the research folks wanted to get at raw data + useful annotations rather than us making these kinds of semantic decisions of what counts as enrollment. After all, there was certainly an _intent_ to enroll in the scenario where they back out before actually purchasing (they clicked on the enroll button, chose a track, and took pictures).

You guys are a lot more in touch with research staff than I am though, so I leave it you. I just wanted to make sure that you knew these scenarios existed.
