In the context of using the Stages to raise and answer questions about power. People often buy the Stages for its (relatively) low price, but subsequently are puzzled by some aspect of the data they collect. They're undervaluing good quality power data. Many power meter users, not just Stages owners, claim that consistency is what matters, not accuracy or precision. The OP appears to have noticed a consistent pattern of varying behavior in the power reported at a constant speed while varying gear ratios, which challenges physics.
Not everyone needs high quality data from their power meter but there's danger in using lower quality data to try to overturn physics. If you're trying to overturn physics, you need accuracy and precision, too. That's why when someone presents a power conundrum you can save a lot of time if the first question is "which power meter are you using?"
