Freestyle Libre - awesome tool, but how crazy is it for you? Do you know why?

Disclaimer: I really love my freestyle libre. It removes SO much burden from diabetes management.

BUT... every so often, they go nuts on me, with the readings bottoming-out, or topping-out, despite BG readings being fine.

Does anyone know why this is? Since the Libre takes readings from interstial fluid, and I'm on keto which can lead to dehydration if you're not careful (which I'm not -- my fault), I assume it's going nuts because I'm not getting enough fluid to the intercell skin areas it's trying to monitor.

Does that make sense?
