Rebel 16.2 beta

Subject: Rebel 16.2 beta Tue Feb 14, 2023 1:22 pm

Got this from Thorsten who is testing the beta version. No considerable elo changes or it must be the time control and/or permanent brain. First test, I understand more is coming.

Very soon all the Neural Net chess engines will have the same Elo rating. In my test the top 3 chess engines have a Elo difference of 7 Elo. lol!

Hardware does not matter much. Over threading the NN with too many threads. Does seem to have a negative impact on performance. Most likely caused by the programmers not testing the engines with huge thread loading. And correcting the issues.
