VWAR (Volume Weighted Average Rating) is a new method of calculating a submission's overall CSA rating by taking into account the number of assessments as well as their values. The VWAR was introduced in recognition of the fact that submissions with more assessments are generally better - that is to say, a shortage of assessments is an assessment in itself. The previous calculation method meant that an unpopular submission with five 10/10s (overall 10/10) could out-rate a popular submission with twenty-eight 10/10s and two 9/10s (overall 9.9/10).
a = Assessments Aggregate
The sum of all assessments made on the submission. If a submission has two 10/10s and three 8/10s, then the aggregate is 10+10+8+8+8 = 44.
b = Number of Assessments
The number of assessments the submission has received.
c = Category's Record Number of Assessments
The submission's category's average number of assessments per submission. For popular categories, this will be higher, and for less popular games it will be smaller. This variable ensures less popular games are not penalized.
