DRV110 The hold current is weak

Hi Team,

The customer is using DRV110 and the attachment is the schematic. And the customer is using the 8pin IC. He refer . 

Q: He tests the hold current is 50mA ,and Ipeak is 2A.  On page17 of tidu578.pdf, we can see the formula for Ihold. Ihold=2A*0.35=0.7A. So the customer confuses the test hold current is weaker than the calculated hold current . What is the reason? How to solve the issue?
