How scoring works
Every report and every game in Proton Pulse carries two numbers: a rating (the badge - platinum/gold/silver/bronze/borked) and a confidence (a 0-100% qualifier next to it). The rating comes straight from the yes/no questions on the form - same answers, same badge. Confidence is everything else: how recent the report is, how close the hardware is to yours, how many other reports agree.
Why split them? Because a four-year-old borked report on a game that has been actively patched should still say borked (that's what the community reported), but the page should also tell you the rating is shaky. Old algorithms quietly auto-bumped stale borked to bronze, which hid the signal. The confidence layer makes the caveat explicit.
