Chart for impact of space between panels and roof [RE-wrenches]

[Steve Johnson]

Yes I'm aware of that but I'm referring to a study with a chart that 
shows performance dergradation relative to distance from roof.  Like at 
1", 2", 3" 4", 5",6". 

Since I already know what to do why do I need this? One word.
"Customer"

This is a highly monitored job with temperature sensors etc.
