What is Citation Share?

Citation Share is measured at instance grain and divides by S, the total number of citation instances seen, not the number of answers.

Because it is a share of a whole, tiers sum to exactly 100%. This is the metric most often confused with Citation Rate, and they are not interchangeable: different numerators, different denominators, different questions.
