I feel this warrants a double post. If people don't agree then either I or another mod can merge the two.
5x5x5 expected number of semi-pairs:
When solving 5x5x5, assuming you have no preference between a solved tredge vs. two semi-pairs, then you are expected to have 1 semi-paired edge at the start of edge pairing when solving using the reduction method. This also assumes that you use no techniques to either create or preserve semi-pairs during the building of centers. Proof.
