Richard, I like that you are using your own fingering to perform these exercises. Personally I think it's ok to use some of our own fingerings if it makes it easier to play the pieces, unless there are some reasons that would make it better to use the suggested fingerings. such as developing finger independance. I know that in measure 38 of Malaguena I use left hand fngers 2,3,4 to play the notes(Am) so that finger 1 is ready for the next measure to play the f. It just seems more logical to me and at higher speeds will be easier to perform.I have added my right hand fingering to this section Bars 41 to 43.
I use m a rather than m i a couple of times to avoid reaching i over to the second string.
I have also tried to use the metronome to play these exercises and find it harder than tapping my foot,(probably a bad habit, but helpful for internal rythm).It tends to throw me off and I lose concentration. I have been counting out loud and am nearly confident to post my first attempts.
