Temp control setting

Got my keezer up and running last night. I have the standard Inkbird controller with the probe in a container of water. How many degree temp swing does everyone program their controller for?

I let my temp probe hang so it’s measuring ambient air.

Hang it in air, give it 2 degrees above for cooling and 2 degrees below for heat, and beer temperature will remain constant (except for heat of fermentation of course.)

On it. Thanks guys.
