How long until I know my FL settings are safe?

So I've been testing some different (riskier) FL settings on a couple of my smaller accounts, and for the first couple of days everything is going well. How long do you guys think I should wait until moving these settings to my main accounts? In short, how long until I know these settings are safe and won't get my account banned/blocked?

P.S. The small accounts I'm using are brand new, made only for this testing.

I usually keep things low for a week on new accounts and then do normal settings

That depends on how crazy your settings is.

I usually keep it for 1 week and if everything works I know it's safe
