i agree it's not a math forum but the point is about accuracy - they are presenting it as if it is truthful, when it isn't, which skews the narrative.
and yes i see OP's posts below: you're right in saying that no game is exactly 50/50, but you can't quantify the "advantage" of a certain team. like, in that case, if you do care about form and are trying to illustrate it, KRU looked absolutely horseshit against EG this week - how are they ABOVE 50% of making it given their recent form (literally a day ago)?
point is: these stats on where a team finishes are all based on % of remaining scenarios, not biased perception of form. you can then interpret it however you want: OK, I like KRU, so while they're at 50% right now, me personally, i like them, so I'm gonna give them 58%
you cant just tell everyone "it's 58% bc math" when it's your own opinion

edit: sorry this seems like ragebait, im also not upset at OP because i think any sort of statistical discussion is good, this is just me being precise with language since i got yelled at by my stats prof about conflating the two when it comes to % breakdowns. it's not chance and perceived form, it's literally how many scenarios are left where a team finishes in a Yth position. good discourse comes about when you talk about comparing the %s to your own opinion of the team, which i am all for
