He could be Chopin, himself!
(except I don't like some of the facial expressions)
He seems to mostly use a straight 3 tempo throughout that one. In the 3rd movement of the f minor concerto, he doesn't.
If you want to listen to some really extraordinary interpretations of them go to YT and look for Ignaz Friedman. His Mazurkas are one of a kind and in my opinion he gives a possible account of that famous "Polish" thing you mentioned.
I'm listening to one of them now (63/3), but it seems to be straight 3 also.
Both interpretations are nice, but I still think Zimerman's interpretation of the 3rd movement of the f minor concerto is the only one that deviates from a strict meter. I can't get the Meyerbeer scenario out of my head...but I'm definitely willing to accept that the meter deviation could have been a lot subtler than the Meyerbeer anecdote implies (that would certainly explain why Chopin was originally so frustrated with Meyerbeer's insistence that Chopin played his mazurkas in 4).
