Was sort of an accident, but I finished a run with something like 12300-12400 points and that still rewarded me with the silver medal.

I experimented around and I think the threshold for silver is 12000 points and not 12500 like the category rules say.

While it lasts, here's the timestamped link in a VOD to show 12040 is enough for a silver (plus a few other experiments).

I didn't confirm an exact match of 12000 being good enough, but that's might guess for the Silver threshold and think the Silver category should be adjusted.

It could be? Never actually checked where silver starts. I took over mod well after the rules got created. I can test whenever i can and adjust.
