Only 300 games, 20 games vs each opponent.
All games: 1.c3 {Book.}

General Rule: Stockfish 1st, Lc0 2nd, Dragon 3rd, StockfishClassic 4th.

Anomaly #1:
Two exceptions to the General Rule:

1. Lc0        58.0/100
2. Stockfish  54.0/100
3. SfClassic  53.5/100
4. Dragon     53.0/100
5. Stoofvlees 41.5/100
6. Rubi       40.0/100


Crosstable screenshot below.

Anomaly #2:
Score vs 5. Stoofvlees:
1. Lc0        15.0/20
3. SfClassic  11.5/20
4. Dragon     11.5/20
6. Rubi       10.5/20
1. Stockfish  10.0/20 worst of all (20 draws)


Anomaly #3:
StockfishClassic's performance vs Dragon's performance:
- SfC 1 point better than Dragon vs Lc0, Sf and Rubi, same vs Stoofvlees.
(Then expected loss to Dragon but only 9.5-10.5).

----
The top 4 among each other had 19 or 20 draws out of 20 only!
