Speed Sets & 200%???

[Allset]

So we have been talking in the general section of the forums and come to find out the description on the Speed Sets that says increases by 200% is actual wrong...
Just wonder if this is right or if the sets need to be buffed or the description needs to be changed.
In the video I have a speed set on with 200% movement speed and my friend has around 102%. But if you notice I am not moving 98% faster than him.
