Personally, I use 30 second padding for a lot of normal scheduled recordings, so I won't upvote that one. I double checked before I started using this action that I didn't already have any with 10 second padding.
What about using 40 second padding for job delete and 10 second padding for no job delete?
10s pre-pad + 30s post-pad = 40 second padding
or
30s pre-pad + 10s post-pad = 40 second padding
Seems safer, in that I doubt many users have that combination of padding.
I post-pad some pass recordings 30 or 60 seconds, but rarely ever pre-pad them.
I think no matter what you decide on, to be on the safe side, we should still have a toggle to allow/disallow deleting jobs.
