The 15% tolerance is part of the standard. This is needed to deal with manufacturing tolerances as well as installation issues. (Bending a cable in a tight radius may create impedance discontinuities.) The tolerance figures into various budgets that ensures that a conforming transmitter connected by a conforming cable to a conforming receiver in a conforming electromagnetic environment will operate correctly.The transmission of audio data over USB is not what I would call critical real time, unlike the situation with SPDIF and AES/EBU. USB is packet based and there is no relationship between the USB bit clock and the sampling rate clock used by the DAC to time conversion to analog.
