I bet you all thought this thread was dead and gone, but I have just found this video which might open things up again (sorry!).
It is some South american guy (I think) playing the fastest I have ever seen, supposedly 39bps - I know that is not as fast as the claimed 45bps from that Marcus Paus chap, but this is the fastest I have seen on video.
