How come there's no way to check the rating adjustment when you send a challenge?

I want to know what the rating adjustment is going to be before I send a game challenge. Why doesn't the website show that?

What's the rating adjustment?

How much your rating will change if you win/lose/draw

Oh ooooooof

I didn't even notice that

It's based on a fixed algorithm that factors in the ratings of you and your opponent and how many games you've played, so it's not like the website can't show you what the rating adjustment is going to be before you hit 'send challenge', but for some reason the site designers don't think that information is pertinent to the users?

Yeah idk. That's a good observation on your part tho

after 2 1/2 years you should be able to estimate it.

I was just going to say that I don't like having to guess. I guess it doesn't really matter, but wouldn't it be better if you knew what the rating adjustment was going to be before you committed to playing a game?
