Steem Whales Powering Down Statistics

A post by Hive account@jerrybanfield piqued my interest in a subject I'm sure a lot of others here would be interested in knowing. So I set aside some time to do a little research. The topic was: 

1. What percentage of the top 100, top 500, and top 1000 Steem Power accounts are powering down? For this post, you could calculate this by using a spreadsheet made from https://steemwhales.com/?p=1&s=power to start. Next, copy all the names, and manually coding whether they powered down or not. What I would really like out of this is a clear number I can quote saying "20% of the top 1000 Steem Power accounts are actively powering down today."

Getting the raw data was easy enough, simply copying and pasting the data into a Google doc. But the users powering down needed to be manual entered into the data sheet. Simply using some functions I found the answers I set out to discover.

Hope somebody can get use out of the findings.

I will make the Google doc available if anybody would like to use the information for personal use.
