If those were the first two lanes run, some of the house pattern may still be left on the lane.. To get a true test of the pattern you need to strip only... Run a burn in pair, and then strip/oil the lanes... Even then, you may still get a little of the house shot depending on how well the lane machine is stripping... That is why you need to strip at least 2 times, if not more if you want to get a true idea if the machine is laying it down properly..
Still, I didn't mind the videos, thank you for making them...
