Randy,

Thank you very much for your prompt attention and response.  I appreciate the level of detail your letter provides and given that no further information is available regarding what the lab actually measured (or just what was submitted to them), I agree with your findings.  
Thank you, also, for providing the revised emissions calculations from your 2012 testing.  
Should any other questions arise regarding the 2012 test results we will, again, contact you through Rockwool and NAIMA.

Sincerely,

Steffan Johnson
