My first batch is also 7 days old but is still chugging away pretty hard. Haven't taken a reading yet but it looks like it's still several days from being done. I used a huger starter, but if anything that should have sped mine up. Looks like you finished in a good range though so I wouldn't worry about it. My second batch (pitched on the 5th) is still going bonkers with a blow off tube. I'm trying to decide if I'm going to keep them in primary for a month or rack to secondary around 2 weeks, assuming fermentation is complete, and condition for....??...as long as I can stay patient?
