In A (→GE1FEEE) there are no accidentals before the 6th and 10th notes of the roulade (in relation to a notation with an octave sign in Chopin's times, a possible sign was required only before the 6th note). Formally speaking, it should read b2 and b3, yet in ascending passages Chopin would generally use altered interchangeable notes (cf. e.g. bars 87, 95, 143, 175-178, 247-248, 331-334 in this movement), which suggests a possibility of overlooking naturals resulting in b2 and b3. In the main text we give a version based on an assumption that Chopin's notation does not contain mistakes, adding a cautionary  before b2.
