ADF4360-9 ADIsimPLL does not match with datasheet

I have configured my PLL with next characterist:

 

fREFIN10,00MHZ
B register1446
R register100
fVCO144,60MHZ
A register2
divide-by-2 functionTrue
DivOut36,15MHZ

 

And ADIsimPLL say an external inductor of 31.5nH

 

but with the data of the datasheet(graph and equation) I get 129nH

 

Wich one is correct?
