12 Point Rating System

[beeser]

One of my favorite YouTube channels focusing on airguns is the Airgun Gear Show. In one of the videos the following 12 point rating system is applied to the Air Airms S510 Ultimate Sporter, which received a rating of 6.5. I wonder, are there any air rifles that qualify for a rating of 12? Are there any other items that would expand the list?

Lists like that can look a little personal. I.e. like someone wants to compare all other air guns to their favorite one so they list it's features.

There are items on there I wouldn't use to decide, even if all else was equal. Swivel studs, single shot and anti double feed are irrelevant to me. They could even be a negative. (E.g. Swivel studs look bad unless you plan to install a sling). 

I consider "adjustable" to be a negative quality. I'm mainly a hunter and adding an adjustable length of pull adds tons of weight for very little (if any benefit). 

Qualities like "lightweight", "short", "maneuverable", "balanced", "powerful" can be as important to me as accuracy.
