Alex i rly don't understand why u don't get it.
Let's take next example.
Player named turboboob has elo between 1580-1620 for 80% of time. However sometimes he plays drunk etc and goes down to 1520 points after 2 days of playing. Sometimes also he gets a streak of imabalanced games when there's no way to balance the elo of teams and he gets elo of 1660.
Obviously hangover is finished and he playes a game with 1520 elo he's imba. Same as when lucky balance streak is finished. Both vaules 1520 and 1660 (remember these are just and exmaples) are non representative deviations. Making elo (only for game balancing) as an average elo from past x games would mitigate a risk of having elo different than from range of 1580-1620 (in this particular case) It would obviously lower the risk of having imba games coused by non representative elo.
To be clear couse after reading your post i think U might understood it as an perposition of calculating whole elo only on basis of last 20 games - i will make an example.
Games Elo
1. 1530
2. 1537
3. 1529
4. 1540
5. 1543
6. 1550
7. 1555
8. 1546
9. 1538
10. 1547
11. 1538
12. 1528
13. 1535
14. 1544
15. 1534
16. 1524
here "hangover games start"
17. 1512
18. 1504
19. 1494
20. 1483
What i'm saying is this guy's elo is 80% time in 1520-1550 range. After only few games it goes down to 1480.
Not that big difference? Yes.
But imagine second guy, who's normal elo is 1480 but he had winning streak and he has 1530 now.
Now imagine 4-5 guys like this in one game and in extreme situations (like in game i linked bad in first post, but now proper linke - http://league.btanks.net/game.php?gameid=29132 ) 7-8 guys like this.
Result?
24 min game. 52-12 in kils.
No doubts if we take their average elo from last x games to calculate elo for balance only it would be more reliable.
