On average, how long do you spend in CAS making 1 sim?

I'd have to guess an average of 10 minutes per character in CAS at a time, but like I picked, I do not time myself. Charas I don't care about get the short end of the stick and charas I do get endless nitpicks and updates as DLCs come out. It really adds up for me since I like to play large families, so sometimes I end up spending my entire play time updating Sims in CAS and their houses in BB.
