Brewzilla Gen4 Temperature Control Drivin Me Nutz

[beerisyummy]

Anyone else frustrated with the huge difference in temperature between the bottom of the machine (underneath the false bottom) and the mash itself, particularly towards the top? In my un-scientific way, I understand it as the difference between hot liquid (at the bottom) and a very different substance above the false bottom, whose part-solid-part-liquid mush behaves very differently as a "thermal mass" (if I'm using the term appropriately). I do not think it's a calibration issue: during the boil the readout is somewhere around 212°-214° and I get a MUCH bigger difference than 2° between the machine's readout and what my handheld thermometer says. So bottom line, I can get the temperature sort of evened out with lots of stirring and starting the recirc right away, but it's a pita and I have this nagging feeling that I don't actually know what temperature my mash is at.
Any workarounds I might be missing?
