Before the 1st semiquaver of the last group, GC and FE have no accidental, which, due to the fact that 11 previous notes in the R.H. (together with d
1) were written on the bottom stave, is only an inaccuracy. GE1 added a 
before this note. In turn, the absence of this sign in EE1 (→EE2) and GE2 (→GE3) is a mistake, as in these editions – same as in mUltimate Chopin – the entire part of the R.H. is written in this bar on the top stave.
GC (→GE1) and FE repeated the 
before b, the 2nd semiquaver of the last group. The unnecessary in this context sign was removed in EE and GE2 (→GE3).
