Why the number of "TASK CONSUMED" in dashboard and in history are different?

The dashboard and hisotry pages show the current task consumption and the number of remaining runs, respectively, but these numbers are different.
I assume this is because they are calculated differently, but what logic is used to calculate them?

Task History shows last 30 days calculations.

And Dashboard shows calculation after last Reset of tasks.

I understand. So the task limit is reset on the first of each month, and the amount of remaining tasks is indicated by the "TASKS REMAINING" item on the Dashboard?
