Jim, <BR>
I think this one's the end of the K.E.portion of the roll, just at the point when you initiate the second half of the roll. <BR>

Any roll starts and ends with a rolling element. <BR>
<BR>
The 2 of 4 starts the instant the first 1/4 roll is started and ends the instant the second 1/4 roll ends. <BR>
<BR>
Split the distance between those two events and you have the middle of the knife edge, however short or long it may be.<BR>
