"Sorry to disappoint you, but he already DID just that! " [lowered his publicly stated 'less-than' production cost by a factor of ten as you claimed he would never do] and you think hes doing it again???..lol
This does not make sense, as I and T4O just showed you that he is.
If what you meant to say was "Do you think that the currently stated upper limit ($68/Lb) is still too high?" Then the answer is YES, I believe that actual production costs are similar to those for conventional Bombyx Mori silk, plus a small increment for added security.
