So this according to the blog I can work out my MMR, my Division Modifier, and how many games it'll take to get into Master League.

MMR
P = Rank Points
U = Unspent Bonus Pool
B = Total Bonus Pool (2669 as of 12:21PM KST*)
W = Win Percentage
M = Magic Number
Pp = Rank Point Differential (This is what we're calculating)

What division am I in? Pp = P + U*W*2 - B

My division is: 2739 + 54*52%*2 - 2669 = 126.16 - which means my modifier is +126.
+126 = Diamond B

To work out how many games it'll take to get into Masters with my current win%:
W = Win %
Pp = Rank Point Differential
M = Magic Number
A = Average Win (bonus pool adjusted)*
B = Average Loss
G = Games required for promotion. (This is what we're calculating.)

G = 5 + [M - Pp] / [W*A + (W-1)*B]
How many games will it take? = 5+[475-126] / 52%*3 + (52%-1)*11 = 354 / 1.56 + 5.61 = 232 games

Now if I can increase my win rate to 58% it changes to: 354 / 1.74 + 6.27 = 210 games


There is another factor though that could make this a lot less games. This factor is your Moving average. For example if I win 20 straight games the system will calculate that my current skill level is too easy and therefore promote me.

So I've won 5 in a row - now for the other 15 lulz...

Does the above sound right guys?

yes correct. its quite a bit of math involved, and makes some assumptions, like a constant win-loss rate. whoever wrote the blog is obviously very much a genius. the bonus pool and division tiers serve to make calculations more difficult and confusing.

of note is: constant laddering with no improvement in skill is not going to improve the MMR nor improve promotion chances(of course it can be argued that the more you ladder, the more you learn and improve)

for myself, i'd say that i have improved to around S or A rank diamond level since I first got promoted, but not enough to get master yet.

and for those desperate to get promotions without taking the time and effort, here are some other ways to do so.

1. Maphack
- this is illegal and can get you banned. but i'm certain some people still use it, esp if its just a minimap hack i don't think it can get caught since you won't be camera-panning all day long at the other fellow's base

2. Get someone to play on your account
- people are offering to do it for just USD 20 in ebay
- make friends who are willing to play for you
- only problem is it gets kinda obvious to those around you. 20-30 game winstreaks all of a sudden. the build order and timings shown in the match history which are visible to everyone. your reaction time is almost always fixed. meaning if you usually make your probe at the 3 sec mark, you will make it at the 3 sec mark for almost all games. if someone plays for you and is better, you may well see the probe being constantly made at the 1 sec mark. macro and decision making can improve, but dexterity is very difficult to change overnight.

3. Win-trade yourself
- if you are high diamond and refuse to slog out another 100-200 games, go borrow another acct and play it to your level. then wake up at 4am when there is no one on the ladder and keep on matching yourself for free wins. you'll be matched against yourself since your skill level is the same and you are the only nut awake searching for ladder games on SEA in those 10 or so secs. once you have lost enough games on the loser acct, use it to ladder back up. Rinse and repeat. 20 games later...master icon! and now you can start doing it for the other account the other way round.
