A method and system for dynamically controlling publication of a changing web page. A delta vector of a change in position of a user interface control in a web browser window is invoked. The change in position occurred between a first time before a change to a web page that is already public was received and a second time after the change to the web page was implemented. A click speed component is invoked to obtain information on transition times between user interface controls including the user interface control within a click flow. A user interface control weight value is determined for the user interface control having undergone the change in position. A disruptiveness factor value is determined based on the delta vector and the corresponding user interface control weight. A test pattern to be applied to the changed web page is selected depending on the determined disruptiveness factor.
