Mine seemed to have returned to what it was before. With changing weather (AC usage), cold winter starts, it can be hard to tell for sure. My average is again typically showing over 30 on each tank, for a while I went months without breaking 30, until the last update which was many months ago. I think there may even be a newer one.
