About the data order

[Fishhao123]

Hi, I found some questions about the order of your data. I guess they are organized by the order of (delta dist, delta angle, angle) for each of the 8 items? And I also found it's quite difficult to understand your 'delta dist', what's your measurement unit？I found my 'delta dist' very small. And is it really the distance of one point between current frame and previous frame? I think it too big, and I think it is the distance between different points in the same frame. Thank you.
