Same problem with this report: 2.0 gig in 87 seconds is ONLY 23 MBps (or 204 mega-bits per second) - a speed that CAN be achieved (easily) with current internet backbone speeds. There-in lies the crux of the issue - WAS the backbone 'digitally' close enough to the DNC servr and a supposed hacker to achieve that speed ? (of course the hacker could locate himself wherever needed for best access.)
Note: THIS version of the report adds an additional hedge of 'speed through a hack' - I consider that a 'weak' hedge ... at best.
July 5, 2016: In the early evening, Eastern Daylight Time, someone working in the EDT time zone with a computer directly connected to the DNC server or DNC Local Area Network, copied 1,976 MegaBytes of data in 87 seconds onto an external storage device. That speed is many times faster than what is physically possible with a hack.
That is the entire guts of the anti-hack argument.
Will admit the committee has impressive creds - but creds do not make for legitimate evidence.

Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good ...
