We can find this net only in connection to Fat Fritz.
So 49921 net is the net of Fat Fritz what is usable for Leela or a special net to demonstrate the power of Fat Fritz over Leela - at least if Leela uses this net. May be both of it.
Any comment?

Thanks.
Why did you choose this net for test and why did you not choose other well-known net like 42850, T40B.4-160 or -260, 40.T8.610, etc? In the latter case we can make comparison more easily to earlier tests.

Sergio will either have had it recommended to him, or chosen it due to its high performance rating there.

Really, performance and behavior of 49921 is rather similar to 42850 and 42872.
Thanks for the answers.

Some people say it’s 10-20 elo weaker than 42850, some say it’s about even. I can find tests in the leela chess discord on both sides of this issue. In most cases, various late t40 nets and t40 derived nets are within a few points of each other.

Hey Corres, I was going to tell you about this NN. Its something like 42850 but much stronger.
Do your Testing with it.

One of the weakest net in T40. (Among full trained net).

None of Leela user use it for analysis.
