I think that sampling stops when it gets to the point that additional
samples won't make much difference. It could be that with your settings,
recursion levels beyond 6 would make such a small contribution that they
are dropped. Something like the ADC settings.

Yes. There is an ADC bailout setting specifically for radiosity (separate
from the usual ADC bailout setting). See the MegaPov docs for more info.

It doesn't seem to work like the docs suggest, though. I've set it to 1
and had no real difference on a scene except to smooth out the radiosity
a little. In fact, based on my limited experience, I'd suggest leaving
it set at 1 all the time.
