Are you sure about these numbers? Most monitors refresh at 70-80Hz, so unless you have special display hardware, I'm suspicious of these numbers doubt . I once had a user post to the matplotlib mailing list that xplt was refreshing at 1000 Hz. I think xplt drops plot requests while requests are in the queue, so many of the loops in his iteration were simply dropped. If the plotting library puts draw requests in an idle event handler, accurate refresh rate numbers can be hard to quantify.
