OK here is my HTA check measuring the 2 harmonic distortion across the record on the loong 3150 Hz woe&flutter track on Clearaudio tTRS1007 tes record.
It doen not look like the Baerderwald/Løfgreen theoretical distortions om 2 minima.
The cart is aligned visually by zoomed camera , and the SME template, to get a visually aligned cantilever the cart is twisted slightly inwards at the front of cartridge.
When lowered the cantilever look straight i the air ,but sags slightly to the right side when resting , even with Aintiskate set to 0. This aligment gives very good crosstalk with Wallys Fulcrum (-35/-36db) and less distortion than before I installed Wallys Fulcrum
The alignement below looked better but gave worse crosstalk -40/-24 and more than twice as high distortion on the 3150Hz track
For reference a theoretical HTA distortion
