Thanks for the reply, at least I am not alone.
Only thing I didn't try was to wire each shelf with it's own plug, so I went and got several extension cords & wired each. I plugged a power strip into the VE-200 & plugged in each extension cord. As of now I am within about 3-4 degrees. The lower shelf is finally heating up it's reading 90 inside & the top is 93 with the VE-200 set to 93. Going to lower it to 92 and hopefully everything will be perfect.
