What's your elevation in Ohio? It might be a function of altitude since both probes are the same. A 6 degree difference seems like it might be about right.
I'm in Denver at 5200 feet and water boils at 198. So, roughly, it's a 1 degree change for every 371 foot rise in elevation. At least using Kentucky windage,
If I'm right and that's the cause, I would say your altitude is right around 2,200 feet?
P.S. so, it's not that your probes are off, it's just that water is boiling at 206 degrees rather than 212 degrees. If that's the case, you're good to go.
