"it must have been munching matter at close to the maximum physically possible rate"
That "maximum possible rate" sure sounds like bullshit.
Why does it sound like BS? Given that a huge fraction of the matter spiraling into the black hole is converted into energy before it falls in, that creates an outward pressure that limits how much more matter can follow. So there is a maximum rate that the black hole can accumulate mass.
