The version of FE (→EE1) is almost certainly a result of an oversight of the engraver, although the lack of Chopin's intervention both in the subsequent proofreading of FE and the pupils' copies is surprising. According to us, in the case of the proofreading of FE1, three changes in the 2nd half of the bar could have distracted Chopin to such an extent that, occupied with developing the details of the notation, he did not notice striking mistakes both at the beginning of the bar and in the next one, while the proofreading of FE2 was only of a random nature. Out of three pupils' copies, only FED bears traces of the 1st movement of the Concerto having been worked on with Chopin, so the lack of corrections is nothing particular, especially that also there Chopin took care of correcting mistakes in immediate vicinity (in bar 139).
