PH issue

I'm finding that the muriatic acid additions to my pool never really match what the Pool Math is suggesting. I thought my acid was somehow bad and tried a new container with similar results. For example, I had 8.1 yesterday morning, and added 8 ounces of 31.45 (20 Be) acid. I was aiming for a 7.2 PH. After re-test it only dropped to 7.8. My FC, CYA and other tests are fine. I wonder if the TA is off? I didn't test that recently since it's essentially shut down.
