This plugin displays various metrics about the trello board, at individual card list level as well as board level. It calculates individual card weights based on the number of todo items [considers each todo item as a story point] and this weight is used to calculate different statistical data.

It calculates the average of your average completion rate and the length of the time to finish your task. This number can be used to represent how far your task is from completion.

For each card list, it also calculates the average weight for each completed tasks [or stories] as well as the total weight of all tasks. It also calculates the number of tasks for each completed story [for stories that contain more than one story point].
