Single post in Contests

Does anyone here know for sure if Affection influences Contests in any way? If yes, what way? It does not appear to figure obviously into the stats for a Pokémon’s Contest’s ranked score, yet the Affection meter is located in a Pokémon’s Contest section. If it does not affect the outcome, why is it located where it is? This is confusing to me. Sometimes obvious things elude me, so I thought I would ask folks who score well in Contests and are “in the know.”
