It does help from my experience with using the cooling cycle.I have not. I have an older Brinsea and I saw the feature on it but assumed it wasn't for chicken eggs as I'd never heard of it, until you. Like @2ndTink, I just don't know enough about it but might give it a whirl on the next batch in Jan/Feb. I'm of the mind that if it's not broke, don't fix it, but perhaps there's still something to be said for giving this a try. I highly doubt it would hurt the eggs, and who knows, maybe it'll help!
