The notation of GC, representing the abbreviated notation of [A], indicates, according to us, two 
signs. A similar conclusion was reached by the reviser of GE2mar (→GE2), whereas FE and GE1 give a hairpin only in bar 7. Interestingly, in an analogous situation in bars 11-12, all editions put the indications in both bars (yet they differ in the way of considering the pedalling). As far as the range of the signs is concerned, in the main text we adopt the averaged signs of GC and FE, as the present between them one semiquaver difference seems to be unimportant. The longer signs of GE and shorter of EE are probably an inaccuracy of interpretation of the base texts.
