Thank you andrew, I really appreciated your comments, because it's clear that you have a deep knowledge of this piece (even accenti and quavers!!). I read that the second Polonaise was one of those pieces that Liszt refused to hear in his masterclasses, because nobody could play it as he wanted: thus, why should I not accept criticism??
As to the quavers in the points you indicated, I obviously agree with you. I believe that this is a deviation I involuntary took over the years, forgetting the original score since I read it for the first time, about 15 years ago.
But as regards the starting of the double notes at 6:30, I confirm that I purposely slow down and gradually accelerate, for stylistical reasons. I mean: I found these staccato double notes very humorous, differently from the immediately preceding passage, and that's why I feel to play them in that way. And fortunately it's easier, because the right hand can breathe!!
