Lens review on PF

Hope this is a good place to ask. I was checking on a Vivitar 70-210/4.5-5.6. User rating is 6.80. However the numbers for sharpness etc was 8.0 and value 8.5. Who put up the ratings...8.0 and the 8.5? I always though they go together. An average of sorts.

The sub ratings are not averaged and then displayed as the overall rating. Rather, the overall rating is the average of each reviewer's overall rating (a separate bubble). This will most likely be changed later on, but for now that's how it is.

Thanks Adam, I did figure out the 6.80 part but was wondering about 8 and 8.5. I think the user rating should be my first consideration. Just notice(maybe for the first time) on another lens that only had user ratings. I always go there before I buy. Another great feature. Many thanks to all who review their items. Hopefully, I'll know enough to add my own reviews.

Some reviews pre-date our sub-rating system, so that's why only the first two reviews have them. The rest are just ignored.
