Description
For Edited Objects, [this area around Hayward label](https://mapbox.github.io/osm-analysis-dashboard/#lat=37.638&lon=-121.962&zoom=9.991&startYear=2010-Q1&endYear=2010-Q4&filterProperty=editCount) has tiles with value>2000 show up the same color as value=600, but a tile above with value=1815 shows up darker.
@jenningsanderson Any idea why this might be the case? Looking at the opacity, it seems to be that there might be multiple tiles in the same location (overlapping).

Research direction
Start with the linked dashboard view around the Hayward label and inspect how tile values, color ramps, and opacity are rendered. Compare the tiles above 2000, at 600, and at 1815; done means the color and opacity consistently reflect the values without an overlapping-tile artifact.
