I'm not trying to pick at anyone by asking those questions. But really there is no standard. We'll take the AR since it's a hot topic right now. Within that platform there's 5rd, 10rd, 20rd, 30rd, 40rd, D60, surfire 60 and 100. None of these should be termed high capacity. It's true that the D60 has a higher capacity than those that have less but when there's no standard to compare against then it's just exactly what it is, a D60 magazine. I believe Jim Sullivan made a comment about "high capacity" just being a made up phrase. A mag is simply something used to feed a firearm. Some can hold more boolits than others
