A (→GC,FE1) has no naturals before the upper notes of the 4th and 12th semiquaver (b1 and b2). This inaccuracy, characteristic of Chopin, was gradually corrected in FE – the first 
was added in FE2, the second in FE3. All these sources have no before the 7th L.H. note, b. This, however, is not an error because a b in the 2nd R.H. semiquaver is placed with the appropriate on the lower staff. The remaining editions have a fully correct text.
Moreover, in the main text we remove the 
repeated before g
1 in the 8th semiquaver, present in all the sources.
