Plug-ins 

　　 Plug idea

　　Plug-in will affect the implementation of the results, but will not exceed a maximum of 2.2%

A brief research shows that benchmark results are affected, but not that much. The whole research is described in Research results. 
Long story short, the maximum means difference observed was 2.2%.
