SSS MAT BENEFIT FOR MISCARRIAGE COMPUTATION

Hi, I need some insights on how the computation of SSS benefits for miscarriage. I had miscarriage last month (Dec.16). EDD should be Jun 2020. I have duly filed my MAT1 last year. My salary is max, so as per New SSS CONTRI TABLE, the MSC should be 20,000. I got the computation coming from the HR and upon checking, the MSC they used is 16,000 (from old SSS table). Tama ba yung ginamit nilang MSC? Based sa contributions ko, tumaas ang contributions ko starting April due to the NEW TABLE, so I was thinking dapat ang MSC na ginamit should be 20,000 not 16,000. ?
