Real world example.
I have since learned how to use my multimeter

0:00 Introduction
2:40 Holding (idle) maximum current draw @ 24V
3:56 8 RPM maximum current draw @ 24V
4:58 400 RPM maximum current draw @ 24V
6:20 800 RPM maximum current draw @ 24V
8:44 gCode real time current draw @ 24V
9:58 gCode (with load) real time current draw @ 24V
11:45 Conclusion

Latests tests with heavy load at 2400 RPM show a maximum power consumption of 12W / motor.
