Currently, there is a thread running on the Escort Radar Forums regarding this very issue. MEM-TEK
has also contributed in that thread, and both he and the Escort representative are putting forward some very interesting thoughts, to include real-world observations, real-world/semi-quantitative testing of various materials, non-quantitative real-world observations, as well as coupled with quantitative laboratory testing of the Escort representative's own "behind the skin" setup.
