Currently, tiles will support sum, min, max, and average. Standard deviation would show the performance variation around the average, which would give the users a sense of repeatable performance. This could indicate either additional training needed, or that the particular task is too difficult to predict accurately. There are other uses, but this would convey some very useful information to users.
