just did my 90 day, and always for years , they staple receipt in passport with next date due clearly visible, then I also add it to my ph calendar to provide a warning in advance of due date.
when extending "retirement" Visa, it's clear to see 90 day reporting date does not change. does not change.
but, seems to me, with the amnesty, u could wait until Sept 26.
