In A one can see a deletion before the 1st L.H. crotchet, yet it allows us to decipher the removed element, that is a C1-E tenth. Therefore, this is a self-correction of a frequent mistake in Chopin's autographs consisting in adding too many ledger lines (cf., e.g. the Polonaise in C minor, Op. 26 No. 1, bar 5 or the Nocturne in D, Op. 27 No. 2, bar 44).
