Title: Percentages to win. (MyUberNick)
Post by: P_u..D_gE on January 31, 2012, 15:01
In which is based the percentage of winning when you use !balance command?

I explain myself. I've watched some games and when !balance command is used this message appears.

Sentinel avg. PSR: 1859(39% to win), Scourge avg. PSR: 1884(61% to win)

As I can see, the PSR are almost equal, however, the percentage is not 49-51 as it should be. It's 39%-61%, why is this?

In other game i've seen this.

Sentinel avg. PSR: 1544(48% to win), Scourge avg. PSR: 1544(52% to win)

If both have the same PSR, why one team has more posibilities?

I would like to know in which is based this percentage. Obviously it's not only on PSR because of those facts I've post.

And other problem I've seen is that, when you use !lock "username", the algorithm to !balance doesn't work sometimes. I mean, sometimes you lock someone, you use !rs command and you see:

Sentinel avg. PSR: 1659(37% to win), Scourge avg. PSR: 1694(63% to win)

and then you use !balance command and it says:

Sentinel avg. PSR: 1609(22% to win), Scourge avg. PSR: 1934(88% to win)

Why this happens?

This is all for now, what do you think?

And if MyUberNick reads this and can solve my doubts I'd be glad.

ok dude if there is no problem i can explain the first one (im not sure about the 2nd one)


Sentinel avg. PSR: 1859(39% to win), Scourge avg. PSR: 1884(61% to win)

at this one for example .. the team with the highest psr player gets higher advantage to win i mean you may see in sentinel all players with 1800,1900,1840,1860,1845
scourge all players with 1700,1750,2000,1950,1800

yes the psr avarage is same .. but 2 players with 1700 psr and 2000 psr > 2 players with 1850 and 1850 percentage according to bot ......i rly dont know why though

also depends if some of players with high psr are locked in sentinel or scourge,you can get that kind of balance.

Yep, !lock fucks up balance. If there are few locked ppl, you'll !balance and get some non sence (70-30) but if you swap non locked guys it can get much better...

I am implementing a code on c++ to balance with !lock people. When I finish I'll send to MuN and he will watch it and decide what to do.

Yes, balance algorithm doesn't work properly sometimes when there are locks in place, will be rectified eventually.
