Stockfish github has nice syzygy test

2-6 pieces and up to 80 000 games. But I don't find it anymore. Where is it?

Of course I mean 3-6 piece. And 3-4 gave nothing as SF has basic knowledge.

It was cleverly hidden https://github.com/glinscott/fishtest/wiki/UsefulData.

Elo gain using syzygy

Tested at 10+0.1, with all syzygy WDL files on tmpfs (i.e. RAM), testing using none(0), 4, 5, and 6 man TB in a round-robin tournament (SF10dev).
Rank Name Elo +/- Games Score Draws
1 syzygy6 13 2 82591 51.8% 59.5%
2 syzygy5 2 2 82590 50.3% 59.4%
3 syzygy4 -7 2 82591 49.0% 59.3%
4 syzygy0 -7 2 82592 48.9% 59.4%

Tested at 60+0.6, with all syzygy WDL files on tmpfs (i.e. RAM), testing using none(0) against 6 man TB:

Score of syzygy6 vs syzygy0: 4084 - 3298 - 18510 [0.515] 25892 Elo difference: 10.55 +/- 2.25

So 6 piece = 149 GB data gives STC 20 ELO and LTC 10 ELO. Maybe at tournament level and SMP 5 ELO only :o ! Waste of storage?
