In A the length of both accents is not much different, yet a comparison with analogous bar 228 and 230, as well as 311, 313 and 315, allows us to consider this difference to be significant, hence in the main text we first give a short accent and then a long one. In GE both marks were interpreted as long accents. The absence of the accents in FE (→EE1) proves that they were added to A later, after [FC] had been finished. In EE2 the marks were added on the basis of GE1, interpreting them as common, short accents. See also bar 226 and 228-230.
