In FC (→GE), the fingering is written only in two characteristic places – under the descending chromatic scale in the 2nd half of bar 17, appearing in the Etude for the first time, and at the end of bar 18, where Chopin, at the change of direction of the figuration, indicated a different fingering from the general scheme. More digits in EE1 probably means that, still at the stage of preparing the Stichvorlage manuscripts, the composer considered these indications to be insufficient. Eventually, most probably while proofreading FE, he gave a full fingering of the bottom register and a few further indications for the top. The latter was repeated – without the last digit of the top voice – also in EE2 (→EE3).
