BQ40Z50-R2: bqStudio: How to set "Advanced Charge Algorithm" Charge current "Low, Medium, and "High"

In bqStudio for BQ40Z50-R2, how do I determine the values of charge currents under Current Low, Current Med and Current High for different temo charging?

It seems odd that for default values, the Current Med are higher then the Current High.

I use Samsung INR21700-50E with chem ID 2591 in my pack. 

Thanks,

Tai
