Any guesses for variety?

My neighbor’s tree produces the tiniest, extremely delicious persimmons. Her English isn’t great, so she isn’t able to tell me what tree this is, but I suspect it’s a wild variety that was used as rootstock for a different tree that didn’t make it.

However, this neighbor loves planting trees from seed, and has peach, plum, avocado, and apricot that have grown from seed in her garden. She also has Fuyu and Hachiya persimmons, which I suspect were planted as saplings purchased from a nursery. And then she also has this mystery tree.

I eat as many of the tiny fruit as she offers me. They’re like dates in sweetness and texture, and are good when deep orange all the way through black and wrinkled.

Any guesses of variety would be appreciated. I tried looking up American wild persimmons, and the most likely one (Lotus or Date Plum) look rounder than these, which you can see are oblong and pointed like a Hachiya got zapped by a shrink-ray.
