APY accuracy is in Reg DD at 12 CFR 230.3(f)(2)
"(2) Accuracy. The annual percentage yield (and the annual percentage yield earned) will be considered accurate if not more that one-twentieth of one percentage point (.05%) above or below the annual percentage yield (and the annual percentage yield earned) determined in accordance with the rules in appendix A of this part."
