Before the 8th note of the passage A (→FE→EE) includes a 
(d
2). Chopin did not make any changes in any of the three preserved pupil's copies, hence we give this most certain version, as far as the sources are concerned, as the main one. GE includes a

A possibility of the change having been introduced by Chopin is indicated by the testimony of Mikuli (supported by RC), who in his edition of Polonaises (Kistner, Leipzig) states that at the time of Ms. Rubio learning this piece, Chopin added next to d2 and d3. We bring up this version as a variant.
