No, it raises the field strength, so that breakout occurs
at a lower voltage, more towards the predicted value which
assumes the ceiling is a perfect conductor.

But as I mentioned earlier, removing ceiling and walls
altogether from the model only makes a 20% difference
so I wouldn't expect much improvement, not as much as
I'd hoped for.

Unless...unless the underside of the ceiling is accumulating
a charge that is holding off breakout.  Anyone got any
thoughts?  Is it worth Terry attaching a few square yards
of grounded foil to the ceiling?  I don't think it'll make
much difference unless something funny is happening by way
of the insulated surface of the ceiling collecting charge.

I suppose the ceiling has to be the first thing to look
at, since it's the closest thing to the sphere terminal.
