Screen Time Accuracy Test

\n \n

${accuracy ? '✅ ACCURACY TEST PASSED' : '❌ ACCURACY TEST FAILED'}

Algorithm ${accuracy ? 'successfully hits' : 'failed to hit'} the exact screen time target.

Metric	Value	Notes
Total Reported Screen Time	${totalRecorded} min	From latest record
Before 7:00 AM	${before7am.toFixed(1)} min	Outside grid window
After 11:40 PM	${after1140pm.toFixed(1)} min	Outside grid window
Expected in Grid	${expectedInGrid.toFixed(1)} min	Target for algorithm
Actual in Grid	${finalTotal.toFixed(1)} min	Algorithm result
Difference	${(finalTotal - expectedInGrid).toFixed(3)} min	${Math.abs(finalTotal - expectedInGrid) < 0.01 ? '✅ Perfect' : '⚠️ Off target'}
Active Blocks	${activeBlocks}	Blocks with >0.01 min usage
Adjustment Applied	${adjustment.toFixed(3)} min	Correction for accuracy

Algorithm Status

Accuracy: ${accuracy ? 'Perfect (±0.01 min)' : `Off by ${Math.abs(finalTotal - expectedInGrid).toFixed(3)} min`}

Grid Utilization: ${activeBlocks}/100 blocks active

Backfilled Usage: ${backfilledUsage.toFixed(1)} min

Remaining Overflow: ${backlog.toFixed(1)} min
