Actually it’s a flaw in the design then.
With audio processing, the solution is/was to cap the result at the maximum value and not let it be “truncated” or “wrapped”... the same should be done here.
Given particular details of the China ren’s photos,
that explanation is thoroughly inadequate . . .
as usual.
