Context
Struck tallies the day on his fingers — an hour run, drills, two matches, weight machines under Loach's eye — and totals it: "five hours of vigorous nonstop straight-out motion," "sustained and strenuous exertion." The regimen quantified in hours of load, the body accounted like a machine logging duty-cycle. The bookkeeping is the point: the academy's demand on the body is measurable, relentless, and stacked the week before midterms, exactly as the fatigue-talk keeps circling back to.
