RD, no one in RRTC is getting rich from certifying courses, believe me.
The state certifiers get $20 per course, of which they get to keep $17 to pay for their time reviewing the paperwork, making copies of the maps and certs, postage, etc. Aside from places like Texas and CA, it's maybe 20 course/year.
The extra $3 goes to the regional Vice Chairs ($1) and national registrar ($2). The VCs review the state certifier's work, and kick back any certs that aren't up to snuff. They pass the certs on to the registrar, who scans every map and cert into electronic form, then passes it on to USATF's webmaster for posting to search engine.
The actual course measurer can charge whatever he/she wants. Now, an RD could negotiate that as part of the fee the measurer will be there on race day to set up the start/finish, cones, mile marks, etc. I know as a measurer I'd damn sure charge more for that. So it's the race's choice - pay the extra, or just be a little careful when they lay out the course.
Part if the requirements for course maps is that they be clear enough that anyone could set up the course based solely on the map, so it would seem that someone with a vested interest in doing that (e.g. the race organizers) would take the extra 10 minutes to do so. I also know that some of them don't, but I feel they are in the very, very small minority. I think that's where you and I differ; you feel innacurate "certified" courses are common - I think they're very rare.
Last year there 1,428 courses certified - how many of those have you or anyone heard about coming up short?
