I play along to the track and write various scribbles on a piece of A4 as I go, sometimes I'll keep playing with hammer ons and sometimes I'll pause the track to write something down.
The chart ends up as a combination of chord charts, root notes, notation and little reminders which I'll play through eventually at the end without the pen to make sure it's correct, then I might look at the actual right hand technique, pick, slap, fingers or whatever.
