TPS74801: About the relationship between the calculation formula for vout and vref

Tool/software:

Hi Team,

Q1:Does the "0.8" in the equation (Vout = 0.8 x (1 + R1/R2)) in Figure 7-1 of the datasheet refer to the Vref (MIN:0.796, TYP:0.8, MAX:0.804) listed in the 5.5 Electrical Characteristics section?

Q2: If it is about Vref, should the calculation of Vout be as follows?
 Vout(MAX) = 0.804 x (1 + R1MAX/R2MIN)
 Vout(MIN) = 0.796 x (1+ R1MIN / R2MAX)
