Unless I'm mistaken, there's something missing in the study. The "test
users" had VE enabled, whereas the "control users" has VE disabled.
The study seems to assume that "test users" always used VE, when in fact
they had the choice to use it or not.
Since it seems that a good proportion of new users with VE enabled are
actually using VE, the difference between the 2 sets of users may be
greatly decreased by the fact that many users in the test population are
using the wikitext editor.
Can you explain if I misread the study, or how you took that into account ?
