The shortening of the 
sign in FE is rather certainly the result of the text's layout – bar 93 starts a new line. However, it is difficult to establish the cause for the shortening of the sign in GC. The copyist could e.g. have mistaken these bars with bars 94-95 where A has a shorter sign. We regard the inaccuracies – in relation to the Stichvorlage – of the hairpins in GE and EE as the effect of a routine adjusting of the signs to the rhythmical structures. We give the A notation in the main text.
