Taichung all-time #
The top all-time mappers in Taichung ranked by overall score.
How is the ranking computed?
Rank is an overall score that rewards a balance of labels placed, distance explored, and label accuracy — so steady, high-quality mapping counts for more than sheer volume. That's why the label counts below aren't in strict order. (The weekly and team boards use the same score.)
| # | Mapper | Labels | Missions | Distance | Accuracy |
