CeeWhy est. now = last CeeWhy count + China deliveries to CeeWhy since that count − CeeWhy retrievals since that count. Office est. now = last office count + everything delivered on site since that count — CeeWhy retrievals and direct supplier deliveries to the Office or any shop (what you use isn't logged, so it only goes up between counts — count again to reset it). The small line under a last count shows what changed since the count before. Quantities are total units. Hover an estimate to see the working.
