RTN tollerance

What is the fastest you have seen RTN take place?
Couple of hours on a frag

Is it worth taking a chance to see if the coral will recover before taking action?
IPersonally, I would put a little super glue over the edge of the good flesh to stop the RTN.

Is there any way to tell that the necrosis has stopped?
Just watch it...

Recently one of my frags got bumped and came unglued from the rock; I pulled it out of the tank so I could reapply some super glue. I noticed that it was growing over a piece of detritus so I picked it out then I reglued it to the rock. That same day I noticed some necrosis ( which was probably started by me picking out the detritus ) at the bottom of the frag where I picked out the detritus. I watched it closely for a few hours and it seemed to stop getting any worse. I wasn't sure what to do, I didn't want to wake up to find that RTN had taken the whole frag, so I applied some super glue to cover the part that had died just to be safe. The coral seems fine now and I'm sure that it will grow back over the super glue, but I'm wondering if I should have just left it alone and kept and eye on it.
