I still think that will have very, very little effect on whether chain details or not. 233 has done exact center to center for ages in a tube, but a tube that is far larger than the sprocket, so there is nothing constraining the chain top-bottom from coming off.
Chain is pretty tolerant to tension. You can dramatically over tension or under tension it with no issues as long as you maintain good lateral alignment and you aren't right on the upper edge of its load rating. Teams should be focusing on good lateral alignment no matter what style chain drive they run.
There's nothing mystical about running exact c-c chain...
