Expected result calculation?

[DanMcInerney]

Can we get an expected result function?

As in the changes in rating/rd or as in win/loss probability?

Win/loss probability. ``` def expected_result(player_rating, opponent_rating, opponent_rd): q = math.log(10) / 400 g = 1 / math.sqrt(1 + 3 * (q ** 2) * opponent_rd ** 2 / (math.pi ** 2)) e = 1 / (1 + 10 ** (-g * (player_rating - opponent_rating) / 400)) return e ```

Sounds good to me! I have another (unrelated) release I need to finish today and I've got a meeting on Monday but before Tuesday is over I should be able to get to it

I should note I copied this code from ChatGPT. It looks right, but I can't read the mathematical notation in the wikipedia articles about how this is calculated and convert it to Python so you might want to double check it.

is it in? Maybe close the issue if it is in.

Correct me if I'm wrong, but the expected result is the method _E, isn't it?
But I agree that even if it is some nice wrapper would be nice.
