210.21 (B)(3) tells us we can use a 15 receptacle on a 20 amp circuit

now 210.21 (B)(2)table shows if you use a 15 amp receptacle on a 20 amp receptacle you are allowed max 12 amps of plug and cord load on that circuit when you have 2 or more receptacles...correct?

Does this mean continuous 12 amps or 12 amps period?

What about all these 13 amp cord and plug power tools? Is that technically not allowed? Or is it allowed because the 13 amps it could reach is non continuous?

I believe the code does not want more than 12 amps on any receptacle. I would not take that to be continuous but the NEC may have factored that into the requirement. So if you have a cord & plug appliance that is 13 amps and is not continuous then IMO that would be a violation with 15 amp receptacles.
