In FEH, the fingering digits for the 5th and 4th last semiquavers – 1-2 – are written twice, with different pencils. Since it was the same digits that were written twice, it seems that the person who was writing them for the second time did not notice the notation or wanted to enhance its legibility. In both cases, one of the writing persons could have been Chopin, hence we include those digits in the main text. The fingering digit given for the 9th semiquaver in EE is most probably erroneous – we are almost certainly talking about the 2nd finger and not third, as the digit '2' should be understood in the English system of marking fingers.
