The four marks in A are typical long accents, which, however, were reproduced fairly accurately only in FE. The marks in FC are slightly longer, whereas in GE they were adjusted to the length of an entire semiquaver group. In EE, as it was performed in the preceding bar, the marks were considered accents and were doubled (there are separate accents for the right and the left hands).
