How often does frequently contacted google list update ?

[Android Central Question]

My spouse has a girl on his google ‘frequently contacted list’ her name was manually inputted.
How long does it take to appear on the frequently contacted google list? What additional apps are connected to make them appear as a frequent contact?
How often does this list update?
He has now deleted all his ‘frequently contacted’.

FYI...If its about Snooping in other people's privacy, you will waste your time here , as it's not allowed .

Best to talk it out, rather than trying to sneak around the issue.
