Just a little factoid that I thought might be of interest to some people: I was looking over the data from the early March backup of IFDB, and I wanted to see how ratings data was distributed over games.
Although there is a mean average of about 4 ratings per game, the distribution is a typical power law curve in which a few games have tons and a large number of games have few. In fact, as can be seen in the table below, nearly 70% of games have fewer ratings than the mean average, and nearly a third (close to 5000 games!) have no ratings at all.
# ratings percentile
--------- ----------
1 32.00%
2 50.00%
4 69.00%
5 75.00%
7 81.00%
12 90.00%
20 95.00%
63 99.00%
583 100.00%
The tippy top of the distribution is Adam Cadre’s 9:05. IFDB currently shows it with 551 ratings, an artifact (I think) of ratings from deleted users that remain in the ratings data but are not shown by the site.
