BQ27421-G1: bq27421 / Large SOC error during constant current discharge

Hi,

Now the customer evaluate bq27421 and I got only attached plot, so far I have not received log file or golden image. As attached plot, this SOC data has no SOC jump and so it looks good result, but the maximum SOC error during 50mA constant current discharge is approx. 5%. What do you expect the cause of this error? And do you have any idea to fix such error during discharge?
