couldn't find the answer on the site but I looked into True achivments that came first. though I'd imagine there are some differences since there aren't platinums so it would change it a bit.

ACHIEVEMENTS
What is my TA score, and how is it calculated?
Your TrueAchievement score is obtained by taking the base GamerScore value of an achievement and multiplying it by its rarity (the TA Ratio), resulting in a more accurate representation of skill required to obtain it. Because the TrueAchievement score is dependent on the number of people who currently have an achievement, it can change over time.

There are some special rules for unusual achievements:

Achievements worth zero points have a TA score of zero.

DLC achievements are calculated using a formula called the Geometric Mean. The Geometric Mean formula uses a base pool of gamers that is a combination of the DLC population and the known main-game population (specifically, the geometric mean of the two populations, hence the name). The Geometric Mean has the following calculation:

((Gamers With Game * Gamers With DLC)/(Gamers With Achievement^2))^0.25

DLC packs that only add a single achievement look at the base game to determine their value.

Achievements identified by site staff to be impossible to obtain due to developer error have a TA score of zero.

Thanks. I wonder how the TA Ratio is calculated. But anyway, we know what they factor in. It'll be interesting to see what the platinum leaderboard will look like if converted to this formula. Rarity and difficulty are related, so I'm expecting it to be fairly similar.
