I don’t know why trakt.tv has only what appears to be a dislodged rating system. At least it could enable the use of a double system, the actual and a parallel one. The latter based on the actual ratings and data gathered from each episode to derive each season and overall series ratings using applied statistics.
As of now, Sunday, February 25, 2018, 01:41 UTC, the ratings for this show, Seven Seconds, were:
Whole Show (only one season released) gets a 50% with 18 votes,
Season 1 (10 episodes, all released) has an 80% with 2 votes,
Each Episode of the season 1 has a rating between 68% and 77% and 8 episodes out of the 10 received ratings 70% or higher.
Obviously, the TV Show’s, Season’s and Episodes’ ratings don’t seem to add up. To me, they simply don’t make any sense.
The current rating system besides being misleading to most, makes much harder than it should [could] be to find out [make an informed guess] if watching a specific TV Show or Season could be worthwhile or not.
Maybe someone could explain why trakt.tv doesn’t have, at least optionally, a parallel rating system derived from an algorithm –system– which makes mathematical and statistical sense or otherwise be so kind to explain to me how to make sense of the current one, because sincerely I don’t get it at all.
