    It looks like the gauge detected a full charge (taper current is 800mA and the log file shows that the charging current dropped below this for the required time). When it does this, it will record the voltage and temperature and re-run a discharge simulation. It happened that the charge termination measurements (together with the load prediction for this configuration) resulted in slightly less capacity and hence true RM drops a bit.
