BQ34Z100: BQ34z100 for LiFePO4 cell

Part Number: BQ34Z100

Dear experts,

My customer is using BQ34z100 in Li-on cell, and now they are evaluating in LiFePO4 cell. 

Based on my understanding, Lithium iron phosphate cell’s SOC-OCV curve is quite flat, and BQ34z100 doesn’t monitor every cell voltage. So if cell voltage sampling is not accurate enough, even a slight change, will it appear relatively large SOC value change? Since our algorithm still requires a 37.5% DOD drop between qualified OCV points to update, it also requires that the OCV point not fall in the disqualified band.

So what's the tips for their parameter set up? Thanks for your suggestions!
