If you've spent any time on this website, you would notice that all my ratings go up to 14. The reason for this, has to do with how we read number ratings. I view the number "5" true average on a 10 point scale, but most view this number as a bad score; usually rating something 7 as average, and 5 as bad. To make up for this mental discrepancy, I have adjusted my scoring system to be 2 times of 7; 14.
This system of measurement was actually not my idea, my brother came up with this when he was 14 years old. We named it the "lit"-mas scale, as the scale is the same as a litmus test but we're describing how "lit" or cool something is.
