Regarding the 1011Mbps figure: the graph _suggests_ the measurements are compared to powers of two (the axis is in powers of two and the line right next to the bar _suggests_ the maximum would be 1024), so I would be more inclined to believe there may have been a mix-up between mebibits/sec and megabits/sec, or something IEC/SI units related somewhere in the measurements? IMHO I don't think that the author would have any reason to fake the benchmarks (because it actually is an amazing piece of software), but I admit I like to err on the side of "assume good intentions".
