Great Video Series! Congratulations! Unfortunately there is an error in the .Meas command in 7:36. If you multiple current and voltage to calculate the Power you cannot use RMS. Instead use AVG. What is also correct: calculate RMS current and voltage separately. After this you can multiply booth quantities to calculate the Power. You can make a quick Check to compare the Results. There is a good technical article from ADI to calculate the efficiency of a DC/ DC converter with .Step and .meas. Here the same calculation approach is used than in your measurement but with using AVG instead of RMS.
Great learning resource. Fantastic tutorials high lighting stuff I never knew.
Thanks for the video! I'm just starting to pick up LTspice and your videos are really easy to follow and understand.

Great explanations. Thank you!
There are many hidden features here I wasn't aware of!
Thanks a lot
