What is the safest high and safest low for incubating eggs?

From what I have read/heard on a few forums, 87 degrees is a safe low, 90 a safe high.
Personally, I think ball eggs could handle up to 92...but why test it? You risk cooking perfectly good eggs.

And now I risk some serious flaming...but someone who breeds normal x normal should take one egg and see exactly how high it can take.

Just an idea for an experiment.

I can't remember who made the comment last year that they incubate at 86 degrees. The rational was that the eggs incubated for slightly longer (1-4 days) but hatched out bigger and with a better feeding response.

I gave it a shot and successfully hatched out all of my eggs at 86 degrees. They began to pip within 24 hours of each other and the smallest one to hatch was roughly 100 grams. I couldn't complain.

This year with my new incubator up an running I'll have less fluctuation in temperatures and should be able to keep the eggs between 86.5 and 86.9.

I'd rather have a longer incubation time in exchange for (possibly) more robust hatchlings than go with a higher temp. This way if I do experience a temperature spike of a degree or two I don't risk anything getting cooked since 2 degrees will still be within the "safe zone".
