In the version prepared for printing Chopin did not include fingering in these bars, most probably assuming that the performers, remembering very similar combinations fingered in bars 17-22, would easily find the fingering which naturally stems from the figuration's shape. The hint written in FED in bar 72 concerns one figure which does not have its equivalent in the 1st section of the Etude. In EE Fontana added in these bars fingering based on authentic indications in bars 17-22.
