The rhythm written down in FCI in b. 7 and 9 is most probably the first version. It is evidenced by corrections stemming from that same version, visible in A in b. 9. Therefore, one can conclude that FCI contains an earlier version also in b. 8 and 10 and generally later in the Prelude (b. 16-25).
In FC (→GE) a slur is present only in b. 7-8; the missing one in b. 9-10 is an oversight of the copyist. The four-bar slur of FE (→EE) is also a mistake – the engraver could have been confused by the slur of the crossed-out L.H. part written down on the top stave in b. 8.
There is no arpeggio sign in b. 8 in EE1 – the mistake was corrected in EE2.
