Once more... it doesn't matter to me what Thin Blue does. What he shouldn't do is measure power on the sweep with the cursor at the last clipping point, and compare it to my measurement of an amp where I put the clipping point at the knee.
The amp he measures has THD of 1% at his cursor, whereas mine is at 0.001% or 100 times less. Clearly I could have moved the cursor to the right and put it at the top of graph to show "more power." But as I have repeatedly explained, that is not proper.
As to "examining" my methods, all I am reading is that you don't understand them or my explanation of the same. You keep demanding to know power at one distortion level. I showed you that in a different measurement. The sweep method above CAN NOT show you that. It is by accident that OP's measurement landed on 1%. It could end any where it wants.
