BQ27520-G4: ChemID obtained from GPC tool is different from the ChemID in the Chemistry Programming Library

Part Number: BQ27520-G4


I have the following question that need your advises.

The ChemID stated in the Chemistry Programming Library for our battery cell is 2797. We used the value in our golden file.

Recently, we performed a charge/discharge of our system and sent the data file to GPC tool to obtain a ChemID value. 

The recommended value is  3536 and the maximum DOD deviation is 1.42%.

Are you able to tell what is the naximum DOD deviation if we use 2797 for the ChemID?

Attached is the data file cpatured.
