I do channel work with subs all across the country. Skill level varies from sub to sub. In the past I have used 1 hour for a single, 1.5 for a dual, and 2 hours for a quad. I just took the DD102 RCDD course and found that my procedure came in on the high side. If anyone had a work sheet that they used to come in more competitively on a bid I would be really interested. Thank you.
