Tried to follow the 15 second rule and question is did I pass..?

Hello Community ! 

I have built a dashboard on delivery data and intended to show how the performance has been over last 10 days, where the deliveries can take longer, then finally a recommended time range for similar deliveries. I've been staring at this too long to decide -  would the story be clear in a 15-second executive scan /for a pair of fresh eyes?  

Please help and open to any feedback!
