Criticker ranking system has one enormous flaw

Postby MTR » Thu Aug 15, 2019 5:29 pm

Imagine we have hypothetical user A who has only ever ranked 26 movies, each one with different rating from 75 to 100.

Then we have user B who has ranked those 26 movies and gave them exactly the same ratings as user A. But on top of that, user B also ranked additional 75 movies, each one with different rating from 0 to 74.

TCI of user A and user B is over 38 :!:

But quite obviously, it should be 0 :!:


So... I don't know how viable is this outside aforementioned example, but to get the TCI at 0, you would need to calculate percentiles only among shared rated titles. It seems it would also add a lot of new calculations to be made, so it might not be viable for not so big site, but leaving it as it is certainly a bad idea.

Yeah this totally isn't an issue at all.

Honestly I'm okay with the way my PSI appear at the moment as they are usually within a 2 point margin. Though there are many older films/ Japanese films with quite high PSI's that I have very little interest or motivation in watching. (Yes I know I'm a philistine).

Sometimes I just like playing around with data, and asking what if?
I'm currently playing around with an extended version of @uvlalid's example to see where that leads.
