Every engine and setup will be so differant, there is no way to tell what you should be running without using some knock detection devive like detcans or knockamp of sorts.

The only thing i can tell you from what you've written is that you can run the same or more timing past 5k than whet your using as ve wil be dropping off. ei if you don't have det at 5k with 18deg then you shouldn't have any det at 6k with 18deg. Dropping timing down like that past 5k will just make less power and cause higher egt's
