Diffuser plate and shelf question

Hi all,

my build is coming along nicely. I have a question regarding the diffuser plate and shelf spacing. Is there a science to the positioning of the diffuser plate about the element? And then how high above that to start my shelving? Also does the thickness of the diffuser plate matter? I’ve attached a pic to show my setup. Thx.

I am no expert nor am I going to call myself knowledgeable about this subject, but two things.. I dislike and unanswered post and two.. purely in my own unscientific opinion.. yes the thickness of the diffuser plate can take longer to heat up being thicker.. too thin and it can burn through.

As for your racks height.. it depends on if you're going to run a water pan or not.. but I'd start the racks like 4 inches above the diffuser plate.
