Data handling
- The totals use 72 rows: the 83 rows below the header, minus 5 blank rows and 6 duplicate rows.
- Empty cells were not filled. 9 Operating hours cells, 8 Stops cells and 6 Defects count cells are still empty.
- Mean operating hours are divided by the number of months that have a value. They are not divided by 3 months.
- EQ-006 NC lathe C meets conditions 1 to 3, but it has Operating hours recorded only for July (1 month), so condition 4 excluded it from the candidates.
