Changing how I monitor my daily average word count

I track my daily average word count in a number of ways, including yearly and monthly, and more recently, since 9/19. You see that last one in my word count posts. I’ve been adamant that I’m not going to change the start date for that count and I haven’t. Until today.

I decided today to change that column in my spreadsheet to hold a 30 day rolling average instead.

What I realized today is that there’s a problem with using a set start date for the average I’m using to monitor improvements to my daily word count. Over time the average becomes weighed down by the past and the present gets lost. If I have 90 days of numbers, the current 30 days are 1/3 of the average. If I have 180 days of numbers, the current 30 days are only 1/6 of the average. As the history of numbers grows larger, the average becomes less representative of the present and how I’m doing now.

A 30 day rolling average will be much more focused on current progress and will tell me if I’m doing well now and let me to see course corrections more clearly.
