I am having great difficulty understanding the concept of RRG velocity.
In the article “Scripting Guide for Relative Rotation Graphs - Updated” (Scripting Guide for Relative Rotation Graphs® - Updated), Darren writes that velocity is the vector difference - or distance - between the last two data points on the line.
Here is an actual data set:

Can someone explain to me how the velocity or vector is calculated using the above data?
I am completely confused as to what velocity and vector are all about.
We can’t provide the underlying calculation for RRG Velocity, that’s part of RRGs IP. You can see what RRG velocity represents when you compare two codes on an RRG, one with low velocity values, one with high velocity values.
In this example CSL has an RRG velocity of 0.06, you can see the distance between each dot is very small, and on the distance between the arrow and the previous dot is almost zero.
Compare this to NEM, which has significantly larger distances between the dots. The RRG Velocity value between the arrow and the previous dot is 0.77.
That is what RRG Velocity represents, the distance between each point within the tail. (An RRG version of Rate of Change is another way to think about it). The higher the value, the greater the movement from the previous point.
