Table 220-13 is demand factors the code allows to be applied in sizing feeders and or services for nondwelling receptacle loads, not for determining the number of receptacles per branch circuit. For this, you need to look at 220-3(b)(9), (the handbook has an excellent explanation of the article). Use 180VA per strap > 180VA/120V=1.5A per strap > 20A/1.5A per strap = 13.333 straps > 13 straps or devices.
Article 210-21(b)(2), the way I read it, is for the maximum cord-and plug-connected load for each receptacle, (not branch circuit), where the branch circuit has more than one receptacle on it. We as designers and installers lack control in meeting this requirement. It seems to me, this would be imposed on the building occupants after the installation is complete and in use.
