LM5069: About constant settings for overcurrent detection

Part Number: LM5069

Hello,

I would like to ask you a question about LM5069-1.
I set the overcurrent detection constants below. Also, overcurrent detection is 3.8A.
RSNS=18mΩ (variation 0.5%)
R1=39Ω (variation 1%)
R2=10Ω (variation 1%)
The selection conditions for RSNS and R2 are listed in the data sheet, but nothing is written for R1.
Are there any points to be careful about when selecting R1?
Also, please let me know if you have any problems with the constants I have selected.

Best regards,
