While I can understand how this may be beneficial to some, personally I would not find this type of analysis of much value. For what I have to do, there is no correlation between the number of tasks completed and my level of productivity, or the effectiveness of my implementation of GTD. I could accomplish 50 tasks in some days that would have little bearing on what I should be working on, or I could complete 2-3 tasks in some days that would have a tremendous impact on moving my projects forward.

Even assuming that all the tasks I am working on are the best use of my time, not all tasks will take a similar amount of time to complete. Just counting tasks at the end of the day and comparing that number to the day before, or the day before that, does not take into consideration the varying amount of time needed to complete the tasks. I rely more on my daily and weekly reviews to inform my thinking as to how well I am doing what needs to be done.
