Adding opponent APS in bot comparison?

Thanks. It does the trick. Which brings the question: is API published anywhere? I get what I had by looking at the source, but clearly did not look careful enough.

I see that there are dark parts for exchanging with rumble clients too.

No published API, no. That said, with JSON I don't plan to remove any fields. It is possible field might be added though, which is why I wanted to use JSON to begin with.
