SPARC Load

Not all days weigh the same.

SPARC Load measures the cognitive and physical cost of your day not how many things you have, but what each one actually takes from you.

Log your commitments across eight dimensions: Mental Energy, Physical Energy, Importance, Urgency, Friction, Dependency, Span, and Drain. SPARC calculates a daily load score from 0 to 100 and shows you the shape of your day on a radar chart.

Three bands, one clear signal
Light (0 - 40): Room to think, be flexible, say yes to surprises.
Intense (41 - 70): Executive day. Requires focus and a real recovery window.
Full (71 - 100): Maximum concentration, minimum margin. A day like this needs a light one after.

The eight factors
Mental Energy, Physical Energy, Importance, and Urgency carry percentage weights they form the base cost. Friction and Dependency are adjusters: neutral at their midpoint, they increase the score above it and reduce it below. Span and Drain are multipliers: they don't add load, they amplify it.

Not a calendar
SPARC Load doesn't tell you what to do or when. It measures the cost of what you've already planned, so you can face each day knowing what it will actually ask of you. Log retroactively. Forgot a morning call? Add it in the evening. The score reflects the real weight of the day.
