Was looking at some profiles today and stumbled on this item:
The "posts %" value is a bit confusing. At first I misread the number to mean the number of posts a person has written, but the "8 posts" number in the centre is pretty explicit. Next I thought the trailing "%" might mean that the number represents "percentage of posts participated on". However, looking at my own profile, this doesn't make immediate sense either as 7 of my questions are tagged "Discussion" as well as two posts where I offered an answer, not to mention the various comments. (7 + 2 != 8)
After a whole bunch of exploratory math, it seems this number is calculated by taking the number of posts and dividing it by the number of tags, which is far simpler than I initially considered. In my case, this would be 8 posts across 13 distinct tags on posts containing "Discussion".
8 / 13 = 0.615384...
This still doesn't answer the question of where the 8 is coming from.
With this in mind, I wonder if it would make more sense to have "posts %" relabelled simply as "%". By removing the preceding word, there may be less confusion around the number 🤔
