Op. 2, Variations, complete
In R.H. figurations Chopin considers accidentals to be valid also in adjacent octaves. Therefore, in A there are no flats to the 9th, 12th and 15th semiquavers in bar 298 (a
2, d3, g3), the 14th semiquaver in bar 299 (d3) and the 2nd and 18th semiquavers in bar 300 (d1, c1). All necessary flats were added already in GE (→FE,EE).
There are more accidentals in #ApI than in A, both necessary (3rd, 4th and 6th among those mentioned above, with the omitted flats to d2 in bar 299 and to a1 in bar 300), and unnecessarily repeated ones (flats to g2 at the end of bar 298 and to c2 on the 3rd beat of bar 300, and also a 
to a2 in bar 299), as well as a cautionary to a1 in bar 299).
