Which equation should I use to calculate the MAX16813B OVP resistor?

The Overvoltage Protection section page 22 of datasheet gives details of how a designer should calculate their minimum OVP threshold to choose from. The designer should use this mark and select a value equal to or above this threshold for their OVP value. The designer can then use the equation page 16 for their OVP resistor divider.
