Not sure if this is built into the game or if it's just confirmation bias, but it feels like players go through periods where they are consistently under- or over-performing similar to real life where players get hot and cold. Obviously statistical aberrations happen, but it does feel like if this game just used the straight ratings for every outcome and there wasn't any background factor influencing each player's current state, results would be more evenly spread. Seeing lots of prolonged peaks and valleys for lots of players makes me think they can temporarily get an adjustment to their play, positively or negatively, perhaps based on how they've played in the last few games. Maybe influenced as well by Makeup/Patience/Temper or some combo of the three.
Is there any known info about this, or has it been debunked? What I'm wondering is if there's any value to temporarily benching a cold player like in real life to give them a break and clear their head, and if there's any value to riding a hot hitter or pitcher who is playing above his ratings. Otherwise it makes more sense to just leave your mathematically highest-rated players in all the time regardless of recent results.
