Piotr,
I'm working on some of your awesome lessons. I really enjoy the Ostinato and Triplet etudes.
Also, I recently started looking at an older lesson of yours, "Move Your Little Finger!". I think I may have found a slight discrepancy between the Guitar Pro file and how you play it. On the 5th bar, first and third note in the last quartet of 16th differ (and correspondingly on 13th bar).
Which is the more correct way of playing?
