New Anime Rating System Rework

This is a rework of the new anime rating system, which was previously hosted on GitHub. After issue #6, the system was decided to be reworked and hosted on Google Sheets.

1. Concept
8
All animes are rated based on its impacts on my culture, which consists of emotion and meme (previously named feelings and meme).

Generally, an anime's overall score is calculated based on this formula:
Overall Score = Total Impact Score * Additional Modifications

2. Common Impact Scoring Rules
14
Every impact of an anime is included in the final score (by a weight depends on its type), so there will be a rule for every common types of impact.
In every rules, an impact is often scored by the product of its strength (how much does it impact) and its duration (how long does it impact). However, these values are often inaccurate, due to the fact that human emotions are non-measurable, and animes are usually not logged anywhere. That's why there should always be a standard for every common impact type to make scoring somewhat more accurate.
There will be some unique impacts (for example: political and historical impacts of Oregairu or Your Lie In April, gate-opening impact of Magireco or Lapis Re:Lights) that will be scored without a standard, so there will probably be some error (these impacts will be standardized when it's not unique anymore).

3. Emotional Specific Scoring Rule
21
We can use the old system for emotional scoring (with some adjustments obviously), because emotions are a huge part of old anime scoring. However, we also have to score an emotional impact by its length, so PADS (Post Anime Depression Syndrome, Urban Dictionary), especially its length plays a vital role in high scores.

Therefore, emotion score is calculated as follows:
Raw Emotion Score = Peak Momentary Emotion Score * 0.75 + PADS Length (in days, capped at 5) * 0.5
Emotion Score = Raw Emotion Score * Emotion Score Weight (0.75)

Peak Momentary Emotion Score is scored using this standard

4. Meme Specific Scoring Rule
29
It's very hard to come up with a standard for scoring meme "strength", so it will be rated by a low weight and without a standard. On the other side, an anime's meme duration plays a vital role in scoring anime memes, so memelord animes (like Magireco or Love Live Nijigaku) will probably have high meme score. An anime's meme may be "killed" by another anime (for example: Bandori is kinda killed by Love Live), so they will get some additional score for that.

Thus, meme score is calculated as follows:
Meme Compensation Score (only counted if an anime's meme is killed) = 0.1 * Raw Meme Score of the anime which killed it
Raw Meme Score = Meme Strength Score * 0.2 + Meme Duration Score * 0.8 + Meme Compensation Score
Meme Score = Raw Meme Score * Meme Score Weight (0.25)

Meme Strength Score is scored without a standard, but Meme Duration Score is scored using this

5. Music Specific Scoring Rule
39
Music is always not included in old systems, mostly because of the old POV in anime rating. Although it's included in this system, the weight is still low, due to the fact there will be no standard for music rating.

Music scoring formulas:
Music Score = Raw Music Score * Music Score Weight (0.05)

6. Waifu Specific Scoring Rule
45
All anime girls, which has an impact on my culture (for example: Katou Megumi and Miuna Shiodome), will be included in the rating of their anime's score by a weight of 0.05:

Raw Waifu Score = sigmoid(Relevant Length / Max Relevant Length * 6.0) * 20.0 - 10.0
Waifu Score = Raw Waifu Score * 0.05

Note: Only one anime girl of each anime is included in the anime's score

7. Notes
53
All impacts from source materials (manga, light novels) or franchise (of animes like Love Live Nijigaku or Magireco) will not be included in the final score, but they still somewhat help an anime (Magireco game keeps Iroha Tamaki alive, SIFAS songs make Love Live Nijigaku dominate my music culture, etc.)

There are some animes I watched but I hate it (Re:Zero for example) and if I score them, it would be very unfair. These will be listed in the 'Blacklisted Animes' sheets
