You need shorter pulses than 10 or 5 milliseconds to reduce motion blur down to the level of CRTs. 100 Hz would only be sufficient if the BF takes up > 90% of the time, instead of the usual 50%. What causes motion blur is the frame being held for a period of time. BFI merely reduces that time by half. On CRTs, each pixel is only held for 100 microseconds or so.
