Your choice of the resistor value makes the current distorious a lot bigger.
The current is also in the transformer so not liniair.
Read Radiotron designers handbook for the theory (or Partridge).
And yes it's a problem if you presents results on an open forum like this. At home you can do what you like, no one cares.
You should place a warning that the results are not very usable because of a different "standard" (and read also wrong* standard).
* no bias = wrong for thd and power measurements. Even frequency response could be different but that depends on the design.
