Been doing DTV for about 10 years and if you do 4 rooms in 1 hour or even 1.5 hours even prewire you are not doing everything required to pass QC. i.e fittings behind wall plates, approved barrels in wall plates, hell they require 30 minutes cust ed., also you should not be putting swm pi inline with ird it is known problem it causes problem with MRV so like I said not doing it right and I bet your SIN #s suck bad.
