The sources generally do not differ in the moment of starting the 
sign (in GE it was moved to the beginning of the triplet, adjusting it – according to its manner – to the rhythmic division), whereas the fact of ending the hairpins earlier in FE may influence the interpretation. In the main text we give the signs based on A (and very similar in this respect EE), yet the most probably authentic indications of FE seem to be equally justified.
