Tuning a safety gap . . .

I've just got my NST and finished building my NST "ala Terry Fritz" filter.
I in the process of tuning my safety gaps, but so far i am hearing two
different stories on this newsgroup:

1.  Adjust safety gap just until it doesn't fire.

2.  Adjust safety gap just until it doesn't fire and then move it an
additional "x" fraction of an inch.

So which is it???

Thanks
