Need advice on FollowLiker settings

Hello, I am currently running FL on an account that has been aged for atleast over a year, I was wondering if someone had optimal settings as of today.

Currently: 3.7k followers, 4.2k following

Retrieve existing followers and followings: 260
Ignore all users with no profile picture
Ignore private users

Follow settings: 450-500 daily limit
delay follow 15-20 seconds

Unfollow settings: unfollow after 2 days
daily unfollow limit: 510-710
delay unfollow: 60-120 seconds

any advice given is welcome!
