Re: [WikimediaMobile] Quicker = more edits on mobile

Thanks for this link Nemo! I've discovered a caveat over the weekend which seems to make these results more unreliable. In test A, the success event is logged and then the page reloaded. Concerned that the event might be lost in the page reload and skew the results I decided to look at the 'save' event which is logged whenever the user hits the save button. In comparison the 'success' event is only logged when the save is successful. Pre A-B test, successful save events [1] 0 14350 1 16518 (30868 saves in both groups, 2168 more in group A, 7%) Post A/B test successful save events [2] 0 13462 1 13273 (26735 saves in both groups, 189 more in group B - 0.07%) New users pre A-B test successful save events [3] 0 6216 1 6362 (12578 saves in both groups, 146 more in group A - 1%) New users post A-B test successful save events [4] 0 4870 1 4772 (9642 saves in both groups, 98 more in group B - 1%) These show little variance amongst the groups and lead me to believe that the save data I posted earlier cannot be relied on. I've written a patch to ensue the events get logged appropriately [A] but I think from this my own conclusion is that ajax loading a page via JavaScript after an edit only makes a significant difference (if no difference at all) to the number of edits a user goes on to make. We can probably safely kill it without concern.
