When? When you put the SPOUT chip back in, it tends to advance about 10*.
And the difference from SPOUT in base timing and total timing depends upon myriad variables and even which processor family you're talking about. In general, it's 10-40* beyond the base timing setting.
There's no way to know (unless you datalog). You should see max advance during a cruise type condition. What I think you might want to do is take a look at the WOT spark tables so you can see how much advance you get there.

On the fox I've run the 15* you mentioned (on 87 octane). If it gets real hot outside, you might need to back it down.
Now if you have a 94-95 processor, you'll be lucky to run over 10* base. Those processors are hugely load-based (they can have over 40* advance beyond the SPOUT out setting). Yes, that means they can see over 50* total timing.
For a safe advance point, 12* is pretty safe for a fox on low octane. But no motor is the same so just keep an ear out for pinging.
i seen a neat thing on youtube, its a digital hookup that shows ur timing at all times, i;d love to get one anyone know what there called...easy way to set the timing!
