Intune update rings - Use Deadline settings

Can anyone help with recommended settings for updates rings in Intune, specifically the user deadline settings?

I can currently have Quality updates deferred for 7 days. 
I want to enforce a deadline and grace period for this update ring but a little confused by the settings, I don't think the explanations are the best when you hover the "i" for more information. 

Can anyone suggest the best settings?

I currently have 7 days for the deadline and 2 days for a grace period. 
Do you think we should be setting auto reboot before deadline to yes?

Any advise would be great.
