Error in ELOstat

[Colin-G]

I am getting a minor error with ELOstat.exe
I just finished checking ProDeo 2.2 against my previous best version 1.87 with a 20 game match between them.
v2.2 won by 15.5 to 4.5
I added the results to my database and ran ELOstat
The result for the 2 Engines is shown below.
Since v2.2 has only played games against v1.87, the Average Opponent value for v2.2 should exactly equal the ELO value of v1.87, but it does not.

Code: Select all

     Program                   Elo    +   -   Games   Score   Av.Op.  Draw

  17 ProDeo 2.2              : 2697  132  98    20    77.5 %   2482   45.0

  59 ProDeo 1.87             : 2484   35  35   282    50.9 %   2478   26.6

I just discovered one reason why ProDeo 2.2 beat v1.87 by such a large margin, mentioned in my above post.
For v2.2, the "Ponder = off" in engine config in Arena GUI gets ignored, and has to be set in the ProDeo.eng file, hidden away in the Personal folder.
I only discovered this today, in this post here

v1.87 did not ignore the Arena setting, which was off.
