 > The reason it's set to 500kB is that's the circuit window (so it's not
 impacted by latency).

 No, the reason it's 500KB is because the threshold for Fast used to be
 50KB, and 50KB times 10 seconds = 500KB.

 Remember that we're sending the 500KB over 4 circuits, so it's well under
 the circuit window, per circuit.
