My guess was that it computed from the amount of data that
had been written.  The first buffer gets written in zero time,
and the next few are almost as fast.  Eventually the network
transmit buffers in the kernel get filled up, and things
slow down to the local network speed.  Even later, the entire
transmit window is filled and no more packets can be sent and
things slow down to the real end to end speed.  At each stage,
the computed transmit speed is too high, but starts approaching
the speed of the current limiting factor, but it takes quite
a while before the reported number is at all reasonable.
