45.45 baud is not only allowed in RTTY contesting, it is the Amateur RTTY standard.

The weird number (more precisely 45.454545... baud) comes from the 22.0 ms bit period of the noisy boat anchors that K0RC and W7WHY use :-).

The risk of cranking your transmit baud rate up is that you will be asked for more repeats when SNR is poor, thereby negating the advantage of a shorter transmission.
