The  indication in A is not legible enough and it could have been misunderstood by the engraver. In spite of this, in the main text we give  included in FE (→GE,EE), as the performance indications in FE were undoubtedly controlled by Chopin and even if he did not correct this indication, he certainly had an opportunity to accept it.

There is also a possibility, although, according to us, highly unlikely, that this indication was initially also in FE, in which Chopin, however, changed it to  in the last stage of proofreading. After all, the composer's intention is not obvious here if we take into account the crescendi filling the following 6 bars. The orchestral voices also do not dissipate our doubts, since the cellos and double basses are provided with , yet violins and violas – with  (the remaining voices are devoid of dynamic markings here).
