Timer for charge calculation (MP2607)

Hello,
I would like to know if there is a way to calculate (estimate) the time taken to reach end of charge threshold current for a system composed of the MP2607 (set at 1.5A) and a battery pack (26 800mAh) to define the timer for charge termination (to define C_tmr)?

As the charge current will not be constant because of the charge profil composed of CC and CV charge, it seems to me that it is not really feasible to calculate it (but maybe I ask this question because of lack of knowledge) and the only way to estimate it is to make a test setting a really big time of charge (to “disable” the timer) and check when the measured current reaches end of charge threshold current. Then, the timer for charge should be set a litle bit higher than the time measured. Is his the good way ?
Thank you,
