Summary:
E & R's results are not based on immediate OA but on free access after an embargo of up to a year or more. Theirs is not an estimate of the increase in citation impact that results from immediate Open Access; it is just the increase that results from ending Embargoed Access. In a fast-moving field of science, an access lag of a year can lose a lot of research impact, permanently.
