Jim, I've done the full certification route for several that have said they couldn't afford it, including sending in the check out of my money to the state certifier. Still do, but with more caution.
What I've found is many people getting something "for free" don't do what I've asked in advance. Nothing is more frustrating that going somewhere to measure and finding out you have a 2.5 mile "5K" and no idea how to lengthen it and remain within the permit requirements.
This is great reading, and great pictures from Pete! I am stunned to see those mile marks coming out that close, and you are using 1.001 factor as well! (Are you sure you didn't measure those for them at some point?)
I would definitely encourage folks who like to work in feet to get hold of a tape marked in tenths and hundredths of a foot. You can interpolate between hundredths to get a pretty good fix on thousandths.
Work in metric or imperial? I say bring 'em both on. I'll always use metric to determine final adjustments on a metric-length course, but in giving locations in U.S. I think giving distances in feet will have a better chance of being right, when some random person goes to find the point.
But using metric and standard works best when your calculator will hold a lot of items in memory so you can quickly pull up the sort of constant you want (mine is a Hewlett Packard with Reverse Polish Notation, but there are others).
