^Greenbelt is a training race meaning you can get dropped, crash, flat, stop and get a drink from your car, whatever, and re-enter the race. It doesnt meet the definition of a criterium as it's open to traffic, and although permitted as a series, aside from mass start Cat 5-->4 upgrade starts, results are not applicable to upgrade. That being said, if you have 19 points from non-training races (i.e. real races) to upgrade from Cat 4-->3 and use a result from greenbelt to supplement your resume, the local upgrade coordinator will usually use said result.
