OK
24.0 x 2 = 48 Elo
Result = 123 Elo differents
- 48 = 75 Elo different to ErrorBar after 500 games vs. 20 opponents. Not new for me ... the average is 55 Elo with other opponents (20 opponents with 50 games).
I made some calculations and find out that with 50 games per paring and 26 opponents the ErrorBar is correct. With more opponents the ErrorBar is smaler and with lesser opponents the ErrorBar is bigger.
Different opponents different results.
And a Rating List with lesser opponents ... to read tea leaves is more interesting.
Thats the bad point we have in our rating calculation programs because factor ... quantity of opponents is missing. We are looking on quantity of games only and this is absolutely wrong.

Most interesting is the result we like.
Hard but fact.
Of course the right rating is in the middle ... around 2.840 Elo. I wrote more about it in German language in CSS Forum.
Best

PS: Logical ... with 19 opponents more as 123 Elo ... with more as 20 opponents lesser as 123 Elo.
