Love the 3x10. To make it week-by-week keep the sprints but rotate focus: week 1 G-C-D one-minute changes and straight down-up at 60–80 bpm; week 2 add Em/Am and accent 2 and 4; week 3 learn a two-chord song, and tack on a 5-minute theory snack after practice like the key-of-G chord family or counting subdivisions. Track progress with a simple tempo ladder - when you get 60 clean seconds at a tempo, sticker it and bump 4 bpm - and a 15-second phone clip on day 1 and day 7.
