[NOTE: Fueling beyond the radius oil capacity increases radius at the expense of resistance to underwater damage.
This table is made available to the commander as a supplement to table I for use when increased radius and
decreased resistance to underwater damage are factors in a decision.]

* Table VI is used to adjust the class data in tables I and IA to individual ships.
The ratios were obtained by dividing the steady steaming mean fuel rates of the indicated ships
by the corresponding mean fuel rates given in column (2) of table I.
