Of course I know SF is not deterministic. I have ran test many times with same results!

However, it's important to stress this is a tactical testsuite, not Elo.
Provide example positions. You don't need to share your whole test suite. Just enough positions that I can do many test runs with and see the average times.
I'm not sharing any from my testsuite for obvious reasons - it takes ages to go through a public testsuite and remove cooks / errors etc.

Since this phenomenon is well attested I don't see the point anyway. Even the SF team kindof admitted it on Discord.

However, if I can find tough positions that are sound that I'm not using for testing - I'll share them.
Well attested? :D You've provided *zero* FENs to backup your claim! Any links to the Discord "kindof admitted"? Any FENs from that discussion? Surely at least one actual example was mentioned?

If your testsuite originates from public testsuites and isn't that small, how can sharing a few positions compromise anything? I think it's because you're struggling for evidence.

I downloaded some HTC file with 115 positions and it seems at least all the first 4 positions have more than one winning move so the test suite is bad.

Here is one position when latest stockfish with 6 cores could not find the right move even after an hour and it is a simple mate in 5 that is verified by chest(still did not try stockfish with 2 cores)

However, it's important to stress this is a tactical testsuite, not Elo.
Provide example positions. You don't need to share your whole test suite. Just enough positions that I can do many test runs with and see the average times.
I'm not sharing any from my testsuite for obvious reasons - it takes ages to go through a public testsuite and remove cooks / errors etc.

Since this phenomenon is well attested I don't see the point anyway. Even the SF team kindof admitted it on Discord.

However, if I can find tough positions that are sound that I'm not using for testing - I'll share them.
Well attested? :D You've provided *zero* FENs to backup your claim! Any links to the Discord "kindof admitted"? Any FENs from that discussion? Surely at least one actual example was mentioned?

If your testsuite originates from public testsuites and isn't that small, how can sharing a few positions compromise anything? I think it's because you're struggling for evidence.
I have zero interest in doing your work for you or convincing you. I work with the others who have done the testing and understand this.

Yes this is common. In some cases the idea is good but the position needs tweaking to correct it and that is very slow - it can take a week or so per position. I use Aquarium to look at every legal move because you never know in these quirky positions what will be thrown up.
