Hey everyone, i did a little testing on my flexwatt today and noticed a little difference in temps. i took an empty 6qt tub not being used, taped the probe from the acurite on the hot side inside the tub and left it for an hour on each shelf, i'm only using 3 shelves out of 6 from my rack. now the first shelf measures on the hot side between 92.1* to 92.3* and the second shelf measures on the hot side between 93.5* to 93.7*. i keep the ranco t-stat at 96*,i have not measured the 3rd shelf yet but i will tomorrow. i have each one wired separately but why the difference? should i just tune it down 1* or just keep it the way it is?. Thanx
