Video Flopped because of increase ad breaks?

Hi so I recently uploaded a video more than a week ago and placed about 2 mid roll ad breaks (which were automatically placed by YouTube) for a 10 minute long video. Flash forward to a couple days ago I upload another video, very similar to the one I uploaded over a week ago. Except this time I placed 1-2 more ad breaks. One at 1 minute, ~3 minutes, ~9 minutes, and than one at the end.

I’m wondering if you guys could help me see if this is what causing the video to kind of flop? The average view duration for my week old video is 4:22 (video is 11:52minutes long). For my recent flop, so far it’s 3:39 (video is ~ 11 minutes long).

I have not received the attention retention for the recent video yet but my other one was 36.8%…

Do you guys suggest I lower the ad break or could this just be a coincidence? Maybe my video isn’t actually well received? Let me know if you guys need other details to help me out.
