Scores and percentiles

Post by djross »

Having just switched over to the new percentiles version of Criticker, let's see how the scores stack up against the percentiles. I should mention that I use a thirty-point scale corresponding to the following choices:

    0, 1, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100.

These kind of fit into a standard distribution, but with a spike in going from 45 to 50, and weighted more heavily on the 55 and 60 side than on the 40 and 45 side. I conceive of 50 as indicating a "bare pass" and 91 as indicating a masterpiece.

OK so here's how my scores line up with the percentiles:

    Score of 94 to 100: 99th percentile
    92 to 93: 98th
    91: 97th
    96: 96th
    85: 93rd
    80: 89th
    75: 83rd
    70: 76th
    65: 68th
    60: 60th
    55: 51st
    50: 42nd
    45: 33rd
    40: 26th
    35: 19th
    30: 13th
    25: 7th
    20: 2nd
    0 to 15: 0th

So, as it currently stands (with 3985 rankings), for me a masterpiece (whatever that really means) means any film that is at the 97th percentile or higher, or in other words the top 3% of films I've seen (that should correspond to 120 films with a score of 91, but in fact I have only given 97 films a score of 91 or higher).

My rating scale is close to ten-point system but with some variation: short films are rated on normal ten-point system (10, 20, ..., 100) while feature films are divided a bit above or a bit below (8, 12, 18, 22,..., 92, 98) so in total I have 29 ratings.

100 99
98 99
92 98
90 97
88 95
82 93
80 91
78 87
72 83
70 75
68 67
62 60
60 49
58 38
52 33
50 23
48 14
42 11
40 8
38 4
32 3
30 2
28 1
22 0
20 0
18 0
12 0
10 0
8 0

As can be seen, I'm pretty stingy with my top ratings as well as the bottom (I don't seek out to watch that many bad films but I have enough imagination to distinguish between levels of badness too), so percentages don't match that well the ratings...but turning into percentages helps to distinguish those extreme ratings a bit, before everything rated 80 or above was T10 but now there's a difference between something rated, say, 82 (definitely recommended) and 98 (a masterpiece I adore)...or in the other end between 40 (meeh) and 8 (die a fiery death). On mid-levels I'm not so sure, it's not like there's a huge difference between 62 and 58 but in percentages it is big (well, in tiers it was too).

On PSIs there are significant changes, because I am sting with extreme ratings, so are the predictions, so no longer a bunch of PSIs in 95+

My top PSIs for films are actually at 88, on bold are the ones I have already seen:
The Passion of Joan of Arc (1928)
City Lights (1931)
8½ (1963)
Citizen Kane (1941)
The Godfather: Part II (1974)
Three Colors: Blue (1993)
The Wages of Fear (1953)
Three Colors: Red (1994)

Close-Up (1990)
Fanny and Alexander (1982)
J'accuse! (1919)

...and it's actually not that great a list for my taste, more like something from a film class. Of the ones I have seen, there's two films I actually consider great, two that are quite good actually and four that are kinda ok but far from being some of the best films ever made (of the three unseen, I have high expectations of Fanny and Alexander, J'accuse sounds potentially interesting but I have doubts about Close-Up really being to my taste).
But the films on PSI 82 look like a lot stronger bunch, several great films there and only one or two missteps among the stuff I've seen.

The lowest PSI for films is 25, for Invasion of the Neptune Men (1961), and the low PSIs I have seen on 30-32 films range are for actually bad films.
