Warm-up/Technique:
String Walking exercise (Pumping Nylon pg. 37) with i,m eight notes @ 80 bpm (cut my fingernails so it was harder to get the strings)
String Walking exercise with l quarter notes @ 85 bpm

Right-Hand Velocity (Pumping Nylon pg. 63) with i,m sixteenth notes @ 100 bpm
Same with l, m with sixteenths @ 80 bpm

Repertoire:
Pica Pica
Played @ 70 bpm w metronome while imaging the next measure.

Estrellita
Memorized Part II up to measure 8. Played @ target tempo (it is very slow, so no problems) while imaging the next measure.

Thoughts:
According to The Musician's Way, a composition graduates to developing status once you can play it at a preliminary tempo. I realized that one of the errors plaguing my approach in the past has been that I've prematurely graduated my pieces to the developing status zone before they're ripe for this. With Pica Pica, too, I need to be able to play it expressively, error-free, and calmly enough to be able to image ahead at a preliminary tempo of 70 before I start increasing the pace.
