In A the only accidentals in each of these bars are two flats before the 1st quaver in the R.H. All 9 remaining necessary flats were added already in GE1 (→FE→EE, GE2). All next passages until bar 479 are written in a similarly simplified manner – cf. bars 473, 474-475, 476-477, 478-479. We regard all added accidentals in bars 471-479 as a revision, although it cannot be excluded that Chopin participated, even partially, in proofreading works on GE1.
