I'll Decide ...
On the rare occasions that I have qualified ARs, I don't ever use that "thirds" terminology, nor do I try to lay down "credible areas".
For me, it's about letting the AR signal something that I may have missed or been caught out of position with when it comes to FKs.
@Russell Jones example is a sound approach.
With free kicks, 9 out of 10 times (hopefully) I'm going to be up with play, see it and hopefully blow at the same time my AR signals it. Good all-round sell. For the odd occasion I'm caught out of position or unsighted, my AR needs to have the confidence to flag for it. Laying down "credible areas" during a pre-match may discourage my AR from doing that so I tend not to do it.
