That e-6 is the scientific notation so even smaller…  
Yes it is the cumulative CPU used since starting the app.  
Restating one app wil show that graph only for that app…  
As 5e-6 is 0.00005 it is rounded to 0.00%

What you show is nothing to worry about.

Maybe look at the system load.

Ps also great post [High system load \> 100% - #25 by Rrrr](https://community.homey.app/t/high-system-load-100/36123/25)
