Shuffle mode has known issues with repeating, etc

As of February 2023, it's being investigated by the experts here

Shuffle always selects randomly from the full list. You can use Random play to add files in a random fashion, then with Shuffle disabled you get the Shuffle effect, but all files are played before a file is repeated.

I have a dynamic playlist that plays anything I have if the playcount is zero, and I play this list on Shuffle (random).

I find that Shuffle isn't as random as I expect to be. 6,000+ songs / 700+ artists and very frequently I’ve had a song play from the same artist played only 4 or 5 songs earlier. Sometimes it’s almost like instead of a blind reach into a mixed bag, it's like the list is just bounding around a noisy line, and the noise isn’t noisy enough. (I’m just making up technobabble, here)

Is there a way to tweak this algorithm? Or does Math just say, “YOU think it’s improbable, but it’s often likely to get another song from the same artist/album x songs later...”

Thanks,
