Micro-TLX in two sliders

Capture mental demand + frustration immediately after each run.

NASA-TLX can feel heavy, so we compress it into two sliders that live inside every Analyzer run. It takes <15 seconds yet surfaces fatigue before it wrecks throughput.

How the sliders work

Mental demand (0–100)

35/100

Frustration (0–100)

20/100

Example interpretations

Mental demand 32 / Frustration 18 → Healthy flow; use this as your baseline.

Mental demand 78 / Frustration 65 → Pause, debrief, and check for System-1 autopilot errors.

Keep TLX honest

Add “Log TLX” to your Fair Trial checklist and let the Analyzer remind you—two sliders, ten seconds.
