LMP7721 bias current in Macro

Hi Paul,

This is a follow-up question from below post.

I am doubtful about changing Macro settings of LMP7721Tina-TI model to obtain 3fA bias current as stated in the data sheet. 

R325 model header says " R325 0 100 1e7"  gives 370fA bias current, So if I input " R325 0 100 1e9" gives 3.7fA bias current? But, it says use 1e8 for worst IB. I will appreciate, if you could help me to understand this

Thanks
