The 
hairpins in A are written inaccurately – at the right-hand end, their arms are of different length, hence in GE they reach up to the middle of the 3rd group of semiquavers. The beginning of the sign, at the end of bar 10, also seems to have been added too early, which is indicated by the 
mark, contrary to it, added in bar 10 in a proofreading of GE2, as well as by the hairpins in FE and EE.
