It takes some time to learn and understand, but it isnt too bad.
here's the Linevel for the last frame of my sparring match
LINVEL 0; 50.402974 -40.767163 15.389564 50.250885 -40.275900 15.142650 -1.034669 -1.862235 4.373622 -2.423645 -2.715091 3.941408 -4.083654 -3.055641 4.732380 2.017577 -1.250525 5.001889 4.408402 0.323500 5.024670 6.481529 1.917810 7.345861 -2.739951 -0.961006 10.403541 -8.142930 0.844103 50.372951 -70.635188 25.451451 50.372951 -70.635188 25.451451 7.612428 4.977648 1.368331 3.844137 -4.281274 -3.383239 2.917845 -6.761793 -3.069784 2.668550 -3.451827 -5.100317 1.959270 -7.299512 0.784179 -0.115358 -7.415441 7.630357 -1.551914 0.979048 20.695199 -12.955209 4.751931 20.411427 -5.439873 -6.992983 12.984663
Essentially the numbers work in triplets representing the x,y,z velocity components which correlate to each joint. It would be easier to look at linevel like this
LINVEL 0; (50.402974 -40.767163 15.389564) (50.250885 -40.275900 15.142650) (-1.034669 -1.862235 4.373622) (-2.423645 -2.715091 3.941408) (-4.083654 -3.055641 4.732380) etc etc...
you can compare the placement of the triplets to the joint list in this thread
http://forum.toribash.com/showthread.php?t=9391 to find which triplet represents which joint.
For example, the first one (50.402974 -40.767163 15.389564) represents the neck, the second (50.250885 -40.275900 15.142650) is the chest. etc.
I dont feel like making a picture to represent the positive/negative directions for the x,y,z, but im sure you can find it in one of the replay haxxing tuts.
umm ya, if this doesnt make sense, I just wrote this really quickly.
Also I want more sparring
I wanna see timuchen do something if anything ;o
