Gene,
Just wondering how the counting was done. Does this truly count courses measured in 2013 or just courses with 2013 certification numbers?
I just checked, and I measured and certified 8 courses in 2013 that had other year id's because some part of the course was from an older measurement, and there were 5 other courses in Virginia that were given older year id's. IF the count does not include courses like that, it may explain some of the drop-off in number of courses certified.
