I like it but would flip it. Top row dots, then line through them. Next row of dots goes underneath, so on so forth.
I personally do ~ 1/4 height vertical lines then slash through horizontally. Specifically because of the space efficiency. I also find it more defined when you have a fine pen, as you said dots can get missed, especially on recycled paper.
I use these:
I’m not too sure on how widespread they are, but some websearch hints South America (here), France, and Iberia.
I’ve seen the bottom one only in anime/manga, never IRL. Can’t recall the top one.
If you start with dots in the corners, and end with an “X in a box” you can get up to 10 in the same amount of space.
Problem with dots is that they’re easier to miss. But if you’re accepting them, then…
Same amount of space, up to 20. I didn’t invent this, by the way.
Damn, that’s great, I love it.

I do the box as well. Neater, self contained.
