A lot of the time the mechanism inside of the cluster is the culprit for the gauge being so jumpy. My neighbor, who owns a shop, said that if the gauge reads at all you're fine. Best bet is to install a mechanical gauge if you're worried.
See that's kinda what I figured, that's most likely why the whole range of motion is labeled as 'normal'. Lol.

I guess at some point I'll just invest in a real gauge and sender.
