BQ27426: Initial value of DOD0 for fuelgauge

Tool/software:

Hi TI teams,

After 10 minutes in Relaxation Mode, DOD0 will be updated according to the formula DOD0 = f(OCV, temp).
If the battery has aged, does DOD0 reflect the aging state?
In other words, are the OCV tables in new and aged batteries the same? Does the calculation of f(OCV, temp) change as the battery ages?
