Also, if a methodology change speeds up the slow developers by x%, it will probably speed up the fast developers by x%. One exception to this is when workflow/task splitting is properly done. Then the "good devs" can do the hard stuff, and create the toolset/primitives for the rest to used to build the product. This split will make the "lesser" devs more productive while making the "good devs" the same amount of productive.
