AI is devoid of tempo markings. Generally, there are barely 3 verbal indications in the entire AI: 
in b. 17 and 89 and 
in b. 191; therefore, Chopin apparently abandoned writing more detailed performance indications when it turned out that this autograph would not be a Stichvorlage. Due to the above reason, both here and hereinafter we generally indicate the absence of indications in AI in notes (these versions are suggested as variants only when one of the remaining sources is lacking in indications).
The crossings-out visible in AF over the beginning of the piece prove that Chopin was looking for the best indication of its tempo and character, just like in both previous Mazurkas.
