Everything I pluck is on auto pilot and has been for a very long time. That leaves my conscious brain fully available to work on note choice and timing.
Casting my mind back...
Exercises that cross strings. Repeat until you get it. Do it again a couple more times and then work on another pattern before going back to the first one. Rinse and repeat.
Where's your thumb?
It's a good idea to aim for using alternate fingers, for each note that is on the same string at least.
