ההסבר מתוך החוברת :

The charging current is getting smaller as the process goes to the near end
term of Lithium battery chaging. To finish charging process earlier, this
program eliminate certain term of CV process. Actually, the charging current
will goes to 1/5 from the initial value to end the process while the normal
chaging goes to 1/10 during CV term. The charging capacity may be a bit
smaller than normal charging but the process time will be reduced
