It would require recording from test amplifier dummy load, and playing recorded data again on benchmark unit, thus, subjecting test data again to distortions of benchmark amp (no matter how miniscule they are), speakers, and room acoustics.
As Gusser stated before, TIM issue doesn't make practical sense, and IMHO, it is entirely correct. Someone wanted to make a party, they had a drink and show, now its over.
High stability of the amplifier is much more important factor, and it something that is time to time neglected with aftermath from HF spurious oscillation and loss of clarity to burned components and speaker coils.
