My 4.5-minute micro-chunking routine

To hit Level 4 fluency you need to segment your day into 28 micro-blocks of 6 minutes. Phase 1 is morning commute: 36 Anki reviews exactly. Phase 2: restroom breaks are for conjugation drills (aim for 12 reps). Phase 3: elevator rides are for listening to raw audio at 1.75x speed. If you waste even 120 seconds of idle time you're pushing your N2 target back by 4.3 weeks. Track it on a sheet.
