"Newcomers with the VisualEditor were ~43% less likely to save a single edit than editors with the wikitext editor (x^2=279.4, p<0.001), meaning that Visual Editor presented nearly a 2:1 increase in editing difficulty."
For the record, this datapoint included in the draft (!) analysis was due to faulty instrumentation. The correct numbers show only a marginally significant difference between VisualEditor and wikitext for an edit within 72 hours [1], with the caveats already given in my earlier response.
