In the main text we include the 
indication at the beginning of the piece, in accordance with the way it was reproduced in FE (→GE,EE). In A Chopin most probably used a currently not used manner of placing the indications within their range of validity and not at the beginning.
In AI there is no indication at all. The absence of this and other performance indications is understandable only in the working notation of a piece and can be considered as an expression of Chopin's intention concerning this issue, as at this stage of the creative process the composer did not try to determine and write down all elements of his work. Due to this fact, in the notes concerning the performance indications, we do not consider their absence in AI as an equal version of a given fragment. Particularly when AI is not mentioned in the text of the note, it means that the discussed indication is absent in AI.
