Virginia NRS Certified

Hello everyone (Especially my fellow Virginia Inspectors). Can anyone tell me the relevance of this New Residential Structure (NRS) training. Other than the money train keeping rolling out of my pocket. I just took this training for the second time at a cost of $150.00 and 4 hours of my life I can’t get back. It told me I can look for workmanship defects (Same slides as last year). Well thank you. I would do that anyway on a new home. Please let me know if any of you think this is relevant training!!!
