Does a hide change the temps on the hot side? I didn't have a hide in any of my tubs and the temp on the gun shows 90 and the probe 91-92. When I put hides on the hot sides the accurate probe now shows 93-94. I haven't checked with a gun yet but does the surface temp actually change that much with a hide or is it just the probe? The probe is glued to the bottom inside of the tubs under the paper towels
