Verbal indications

The  indication falls on the 2nd beat of the bar in the sources. It seems highly unlikely that Chopin wanted to indicate exactly this place as the moment of reaching the forte dynamics, therefore, in the main text we propose to put the sign at the beginning of the bar. Chopin probably used here an earlier notation rule, according to which the signs were not placed at the beginning of the area covered by them, but somewhere in the middle. This type of notation can sometimes be encountered in his works. Cf. e.g. the notation of A in Etude in G, Op. 10 No. 5, bar 83.

In the sources the range of cresc. was not specified, yet it is not that obvious. In Chopin's notation, verbal dynamic indications are to a certain extent independent from the hairpins, therefore, it is possible that cresc. is supposed to reach even the beginning of bar 76, in which dim. appears.

Lack of the  mark in EE2 is a part of a bigger mistake – in this edition all dynamic hairpins in bars 71-78 were omitted.
