Looks like percentile. But what is the top box? You have the 'adjusted' percentile - for the weighted average, and the 'raw' percentile for the actual score. And then there's the box on top next to the number of stars given. Looks like it's the average of the two percentile numbers (using an example that has 98 for 'weight' and 95 for 'raw' - with a 97 at the top).
Any reason for that third (top) score? Not planning to incorporate it into the all-time score are we?
It's neat, though. ^.^
