 Drag and drop your pmtiles archive to the pmtiles debugger to see the large tiles on a map. You can also switch to the
 "inspect" tab to inspect an individual tile.
 
-#### Computing Weighted Averages
+#### Computing Weighted Average Tile Sizes
 
 If you compute a straight average tile size, it will be dominated by ocean tiles that no one looks at. You can compute a
 weighted average based on actual usage by joining with a `z, x, y, loads` tile source. For

 You can load these sample weights using duckdb's [httpfs module](https://duckdb.org/docs/extensions/httpfs.html):
