Weekly Consumption Report

Weekly consumption is hidden because the tank data health is too low to trust week-on-week deltas.
Needs at least 4 reportable weeks, health 85%+, and coverage 60%+.
Sampling SEMI_SPARSE
Data Health 82.7%
Bars are shown only for weeks with enough clean coverage. Missing or unreliable weeks are left blank.
