Simulating the fill rates correctly is tough. But getting the timestamps right is also tough. Exchange timestamps are crap. If these there used - that's a possible future leak right there. Standard PC hardware? Remember, that a standard PC clock gives you something like 50ppm. That means - yes - 50 microseconds per second drift. One need their own boxes with stable clocks, GPS, or otherwise synchronized. I doubt that this professor had access to that kind of infrastructure.
