Economy lab — any shape, join at the change
Build a drill cell or a scale-shape run with economy joins. Defaults lean economy + 3NPS + 6 strings, with 2/4/6 presets and 4/4-friendly updowns. Intention: run 3NPS / mode maps with joins — A/B the same shape on Alternate. Lessons: Economy picking (scales job). Learn strict DUDU first on Alternate.

Pick lab
X row: o outside · i inside · = economy join. RH shows D=/U= on joins. Up then down repeats the peak so cells land on even eighths (bars of 4/4).
Practice note
Use after Economy lessons 2–5. Same 2→4→6 presets and 4/4 updown as Alternate lab. Toggle to Alternate to A/B the same shape. Rest-stroke across many strings: Sweep / Sweep lab.
