The metric seems misleading, as it is one-sided. It only checks how many clusters we look through, but not how much of the unnecessary data one needs to examine

The metric seems misleading, as it is one-sided. It only checks how many clusters we look through, but not how much of the unnecessary data one needs to examine. Most indices optimize the amount of data that does not need to be browsed when querying, this index seems to maximize the amount of data that needs to be looked in a linear part of the processing.
