The quality rating is based on 8 categories. The categories are:
Each bootleg gets points for each category, e.g. very good picture quality = 5 points, very bad picture
quality = -3 points. After all categories are rated, the final quality rating is calculated which is shown on the main page.
The best rating is 36 points, only HD pro shots can usually achieve this. 35 points is the maximum for a dvd-video pro-shot. 2 cam audience bootlegs = max 31, 3 cam audience
bootlegs = max 32, the maximum for most 1 cam audience bootlegs is 29 points. In rare cases the rating might be higher. 25 points is still very good for 1 cam audience.
