BQ27426: When to save RA Table values

Part Number:BQ27426

Finally gotten the BQ27426 communicating, configured, and working properly.  I'm not using a golden file and am attempting to implement logic to save the RA tables for restoration after a power loss/dead battery.  Our device is mains powered with a 24 hour battery backup.  (We have a battery charger that keeps the battery SOC at 91%).
I'm wondering when during the "learning cycle" are the RA table values accurate?  If the device is plugged in by the user and reaches 90%, and some time later, is unplugged, and operating on battery, will the RA tables be accurate when the battery is at 50%, 20%, fully depleted?

Thanks for any insight.
