The datasets are pretty small (<=5k docs), which means the indexes are pretty small. With SERVER-103623, we should be able to get pretty good accuracy for index-based CE. From my experimenting, we will also either need to extend index-based CE to handle more kinds of index-bounds (SERVER-103624 e.g. bounds that are not a single, simple interval) or we will need to disable some of the test cases.
