If the tournaments did not have adjudication, if the games were to the natural end, we would see the difference between having or not having Syzygy.
The adjudication helps engines without Syzygy support.
On the other hand an engine with early wdl support, you might find different plans and better results,
difficult to measure.

I don't have any more interesting benchmarks, but Topple gained about 25 elo from syzygy 6 piece tablebases.

I was indeed talking about EGT inside the engine.
25 elo for the 4-5 ?
It seems a very small gain for such a usefull information ...
How much the i/o overhead is responsible for this ?
In Minic, using the 3 men EGT is 0elo ...

Elo gain depends on the engine ending knowledge and a good search.So this would vary from engine to engine.
