225 adjusted rating on his bronze league unknow tier.

- 150 AR from the leagues difference, 75 AR. - 63 AR for him to be an active player, then most likely having a huge enough moving average to skip a tier and then we can probably guess that he was on a S Rank bronze division and went to an A Rank silver division. (as there is only 3 tiers on silver)

This is my best guess, but no, I can't prove anything

I was just wondering. Does sc2ranks now know more about the division rankings of each division? I see a modifier in any division I click on. Like: Division Bucephalus Omega (3054 - 226). While the first value, Division Lenassa Pepper (3230 - 305). Does the second value have something to do with the division tiers?

This isn't really on topic, but I think this is the most suitable place.

Have anyone looked at the equation they put up at the panel discussion at Blizzcon? (look here
start at approx 2:00). I believe it's highly relevant for the MMR calculation part, and also useful for those thinking this is based on easy math.

I wonder if Blizzard will ever release more information on Division tiers and MMR. It seems a little pathetic and worrisome that they are so guarded with simple equation information in their game.

Why are they hiding it? Any reason they have ever given is just a load of crap.

Anyway, on topic, I really enjoy reading this but some of it is still a little above my head. Like how did you determine what kind of division is S-Class and stuff? You don't have to answer b/c I don't think I'll understand it, just thinking out loud a little

Q: How did you arrive at these numbers? What methods did you use?
A: You'll notice that the list of players is numbered in Blizz's Top 200. Some players are tied for the same rank. Because it's been explained that the Top 200 is based on points but without division modifiers applied, that means that all players who are tied for the same rank in the Top 200 all had the same unmodified point totals. The Top 200 doesn't list points, only player records, so you have to work backwards along their match history to determine what their point total was at the time of the snapshot.

For example, if Player A is #100 and his Top 200 record was 50-50, but now it's 53-52, you would look at his current rating, go back in his match history, and start adding back points for losses and subtracting points for wins for his last 5 games. Let's say the result is a rating of 1000 and he's in Division A. If Player B is also tied for #100 and you determine his rating is 800 in Division B, then you know that 800 in Division B is equal to 1000 in Division A. Once enough of these data points surface (and I was jotting them down in that "data points" spoiler section as I found them), patterns begin to emerge.

At first, I found the +126 modifier. Then, I found the +252. Then I found the +315. Then the +63. Then I inferred the +189 (between +170 and 200, and 189 fit the +63 per tier pattern).

That's actually their "race balance" equation, which is what they use each time a P player beats a Z player on X map. They haven't revealed their matchmaking calculation (though it's probably not as complex).
