I don't think it's possible to give you a focal distance down to the inch, it will vary depending on things like how tight it is on your face, the shape of your head, depth of your eyes, all of that effects the position of your eyes and by that exact focal distance.

I wear progressives and the "sweet spot" is hard to find and I struggle to get a clear image. It's not bad, but I think it could be better. I tried a pair of reading glasses and they were useless. Then after reading your post, I tried a another pair I use to play tennis which only have the distance prescription. Oddly enough, the stuff that seems closer to you (the bottom menu bar is a good example) seemed easier to read than with my full prescription glasses. Everything else (I tried video clips, Netflix, game...) seemed similar to what I see with the full prescription glasses. My distance prescription glasses (the tennis ones) are older though and the prescription isn't up to date.
I'm due for an eye exam anyway (last was 2015) so I'll see if I need new glasses. If I need new glasses, I'll be curious to compare the new full prescription with the new distance only glasses.
Thanks for this post, very interesting.

I suspect that the reason glasses with distance prescription worked for stuff that is up close is because the distance that things appear in the Go has little to do with the actual focal distance of the Go. Basically the distances between the screen, the lenses and your eyes, as well as the strength of the lenses creates a specific focal distance your eyes are always focused at while wearing the Go, and anytime something appears to be at a different distance it is actually an illusion caused by showing each eye a different image and doesn't actually affect the focal distance. The reason your distance lenses were better for the bottom menu but the same as progressives for stuff that looked further away is probably because you were trying to read with the near vision part of your lenses when you actually need to be using distance vision for everything.
