Whoa! That sounds like a different course to me, and should be properly measured and certified. It wasn't clear that Jeff's RD even measured it (or how it was done if it was), and with the start on a different road-- I don't understand how you can say this course is still certified. I agree with Jeff's opinion on this.
To me if the start, finish, or anything about the course is different from what is shown on the certified map then it's a different course. If it's a "little bit" different, then that little bit should be measured, and the certifier should use judgement to determine whether to certify the adjustment. I would think it gets a new number as well (?).
