Your issue isn't the accuracy of the APYE, it is the systems accrual. Why is it wrong?
You are saying the disclosures are correct, the problem is that when you calculate the amount of the interest paid, it was to much or to little. That could point to much bigger problem.
We had set an accrual table to the wrong % once. We went back and re-calc'd all the applicable accounts, properly credited them (they were short) and sent corrected statements.
