My goal is to beat 2015 which at the start of 2016 was very doable but I deleted some high traffic videos early in the year that I was paranoid about having copyright problems in the near future. The videos weren't representative of my current content so I had no issues deleting them but my numbers did take a hit as a result as you can see in the view column on this screenshot. The orange bar is 2016 and the drop off is where I deleted those videos.
Even despite deleting those though 2016 is tracking pretty similarly to 2015 in most categories. The top number is 2015 and the bottom number is 2016. So 2016 is ahead in watch time/average view duration/likes/dislikes/shares while 2015 has a pretty big lead in comments and about a 30,000 view lead over 2016. Everything else the differences aren't too big. Slight drop in subscriber gain and videos in playlists but nothing for me to get worried over.
It should be interesting to see where the 2016 numbers finish in comparison to 2015 (Both are scaled January 1st to October 18th by the way) but with a mostly clean slate I will be interested to see if 2017 can beat 2016 even with the 1.5 month boost 2016 got at the start of the year because that will be my goal for 2017 as well to once again try and beat the previous year.
