Technically speaking, you are correct as the code is a bit murky in this area. A device (receptacle, switch etc) by definition does not consume any energy so there is no load added to the circuit by installing any number of receptacles. The problem occurs when too many loads are plugged into those receptacles.
The rule of thumb goes like this:
Because a normal circuit breaker can only be loaded to 80 percent of trip rating, then 0.80 X 15 = 12 Amps. 12 Amps X 120 volts = 1440 Volt-Amps per 15-Amp circuit. 1440 VA / 180 VA per receptacle = 8 duplex receptacles per circuit allowed.
For a 20-Amp circuit, you are allowed (.8 x 20 X 120)/ 180 = up to 10 duplex receptacles per circuit.
A good guideline many electricians follow as a 'rule of thumb' is of 1.5 amps per receptacle which is on the high end of the trip rating, but then again the trip rating is based off CONTINUOUS load. All of the inspectors I have had inspect my own electrical work in three different states has given the advice of no more than 12 receptacles per circuit. Switches are unlimited since they have no current draw.
Chances are 1Myke would be fine, but I would still map out all of the devices on the circuit. You never know what the circuit will already have on it, especially if it is an older home where previous rehabilitation may have taken place.
