The developers of Lc0 and their helpers decided during TCEC 15 Super Final Leela uses the net T40.T8.610

I made some test on my dual GPU machine with this net and with the older net 42176.
The net 42176 was earlier the best against Stockfish.
In a standardized test net T40.T8.610 was valued to 14.9 Rating Score and net 42176 was valued to 7.5 Rating Score.
My system: Ryzen 7 1800x 8x4000 MHz CPU, 24 GB RAM, 2xRTX 2060 GPU, Win 10 64 bits
Common parameters of Leela:
Lc0 version 0.21.1
Threads: 4
Backend: Multiplexing
BackendOptions: backend=cudnn-fp16,(gpu=0),(gpu=1)
NNcacheSize: 5000000
MiniBatchSize: 512
Others are Default
Test 1 - Speed Test: Go Nodes 10000000
Results
Net 42176 max nps = 52392 (Depth 17, Nodes 4492793)
Net T40.T8.160 max nps = 55707 (Depth 18, Nodes 6681918)
Test 2 - Match between Lc0-s using net 42176 and T40.T8.610, respectively.
Played 50 opening positions with reversed color.
TC: 1 min + 2 sec / move
Result
DUALx Lc0-v0.21.1 : DUAL Lc0-v0.21.1 = 4 : 3 (93 draw) 100 games.
Dualx Lc0 used the net 42176 and DUAL Lc0 used the net T40.T8.610.
As we can see in my test the two net are very closed to each other.
At least on my machine the net T40.T8.610 does not seem better than the older net 42176.
